Is it possible to make a custom projectile pass through enemy sprites? I’ve tried reducing the clip size to 0 coupled with the flag that forces it to use the custom clip size but it doesn’t work. Any ideas?

Also is it possible to keep the devastator from shooting 2 projectiles every time it shoots? I’ve adjusted the shots per burst amount and tried everything else I can think of but the sucker shoots 2 projectiles no matter what. Even if I specifically force it to shoot a projectile at a certain frame of the animation. I even set the shoots parameter for it to -1 and force projectiles at certain frames and it still shoots 2 projectiles.

For the projectile you could try applying the NOCLIP flag (htflag 2048) to it after it spawns: https://wiki.eduke32...iki/Spriteflags This might not work on a projectile, though, it might need to be a regular actor, I'm not sure.

For the devastator, make sure you have changed the WEAPON7_FLAGS on it and not just the shots per burst value. But it might just be really hardcoded to fire that second shot, in which case you would have change the player's current weapon slot, at least at the moment of firing.

As a general comment, it seems like you are trying to do a lot of things that go against the grain of the game. With some planning, you might be able to avoid these problems.

Yeah I am definitely trying to make some changes to long standing weapon characteristics, but I don't mind running into walls like these. Better to know the limitations of the engine now and I don't mind wasting time on things that will never come to be due to limitations. I got time right now.

Thanks for the tips.

How do you change the ammo sprite displayed in the HUD for the original weapons? I can't find anything in the wiki regarding these ammo HUD sprites. I'm sure it's something that needs to go into the DISPLAYREST event, but I don't know what to variable to use or change.

If it's a 1:1 change then just swap the art tile for a different one in the .ART file.

Otherwise, you have to disable the entire hardcoded hud display and draw your own from scratch. If you continue modding I'm sure you will end up going that route.

Out of curiosity I was wondering exactly what method the source uses to do this, I believe it's this in sbar.cpp:

                int32_t asprites[MAX_WEAPONS] = { -1, AMMO, SHOTGUNAMMO, BATTERYAMMO,
                    RPGAMMO, HBOMBAMMO, CRYSTALAMMO, DEVISTATORAMMO,
                    TRIPBOMBSPRITE, FREEZEAMMO+1, HBOMBAMMO, GROWAMMO, FLAMETHROWERAMMO+1,
                };

So it is literally those tile names. Theoretically you could `dynamicremap` those tiles and create your own ammo pickup actors, if the only thing on the HUD you wanted to change was what ammo sprite it displayed. Otherwise as you said, sooner or later you're probably gonna want to remake the HUD entirely. For example any weapon taking the place of the Boot can never display ammo because it's hardcoded to -1, and later on when the sprite is rendered to the screen, it checks and fails out for any tile ID less than 0.

[VGames]

My main issue is that the ammo pickup for the railgun is actually the original HEAVYHBOMB actor because it gives you 1 ammo at a time which is perfect. However, this isn't the ammo sprite used in the HUD for the pipe bombs. That sprite is the big box of pipe bombs which is now a Railgun weapon pickup. So, the Railgun Weapon pickup sprite is what's displayed in the HUD instead of the other one. I'll look into this some more. Thanks for the tips.

[jimbob]

why not use the ammobox actor then? and ignore the heavybomb actor. change the amount of ammo you get through the user.con code

if that doesnt work, create your own pickup actor, and let it give you whatever ammo you need to get from it.

[VGames]

What I did was set the ammo and weapon pickup sprites like they would normally be. That fixed the HUD issue. Then I created a new weapon and ammo pickup for my railgun that were created when the original pipebomb and pipebomb ammo pickups were spawned. The originals just get swapped out with the new ones. It's all good now.

Is it possible to change the weapon raise animations? So that maybe u can have a weapon pop out from the side or from above when switching to it instead of it raising up from the bottom of the screen like all the weapons typically do? I didn’t see anything for this in the weapons sample con and I don’t recall any weapons in mods doing this.

You can cancel the hardcoded drawing of the weapon by setting to RETURN to -1 in the weapon drawing event (EVENT_DISPLAYWEAPON or EVENT_DRAWWEAPON). Then you can use rotatesprite and other commands to draw the weapon or whatever else you want to draw on to the screen wherever you want it to be drawn. And that is really the only answer I can give you. There is no simple hack or setting of a variable to make a weapon come in from the side instead of the bottom.

[Reaper_Man]

Yes it's possible. You'd have to completely rewrite the weapon display code for that specific weapon, which sounds harder than it really is, and really is just tedious more than anything. The weapon sample CON would be a good place to start, you'll just have to do your own math on having the weapon pop out from the side or top.

[VGames]

Ok cool I’ll look into this. I’ve been working out of the weapon sample CON extensively already so I’ll keep adding to it. Thanks.

[VGames]

ok I've got a little issue with 2 weapons playing off the same weapon using the WORKSLIKE command. They both WORKSLIKE weapon 11 and I got them to play the raise and lower animations like they should as long as you aren't switching between them. When you switch from one of them to the other the art for both weapons will be displayed during the lowering animation of which ever one is currently selected. I have tried everything to get them to wait on each other to finish their lowering animations before displayign their own art but it just won't work. I can't think of a proper if statement or variables to get them to wait on each other.

in the CHANGEWEAPON EVENT I'm using this to set up the wait:

ifvare player[].curr_weapon HANDBOMB_WEAPON
	setvar SwitchTime6 20

ifvare player[].curr_weapon TRIPBOMB_WEAPON
	setvar SwitchTime9 20

in the DISPLAYWEAPON EVENT I got this to make them play the proper animation when their specific SwitchTime variable is active:

	ifvarg SwitchTime6 0
		state draw_LSFire1

	ifvarg SwitchTime9 0
		state draw_4HFire

Now both SwitchTime6 and 9 get reduced by 1 every tick when above 0 I just didn't show that part of the code. This code works good unless you're switching between both weapons. I didn't include all the various sets of script I tried out to try and get them to wait on each other. They were all worthless. Please help if you can.

[Danukem]

I'm going to guess that one instance of the weapon drawing is the hardcoded one, and the other instance is your own using a screen drawing command. If that's right then there's a few tics where you aren't cancelling the hardcoded display event.

In cases where the coder doesn't know what is going on or causing the issue, I kind of have to discount what they are saying about it since what they are saying could include false assumptions. So I can't go by your descriptions, only the actual code, and you didn't include the main part of your code. I don't have time anyway though.

I wanted to share another standalone-ish effect we have in AWOL ahead of release - This is an enemy arena spawner / manager to spawn in waves of enemies in an automatic and dynamic way. Think of it like a much more advanced RESPAWN. From the code documentation:

-----------------------------------------------------------------------------
Summary :
Combat arena management and spawning.

Arena Managers act like Touchplates, activating when a player enters their
sector. Arena Spawn Points act like Respawns, except they can spawn multiple
times. Once activated, a Manager will attempt to trigger their paired
Spawn Points in waves on a repeating cycle. Each wave, a Spawn Point will
only trigger if its spawned child is dead, otherwise it will be skipped.
Spawn Points will continue spawning until their "tickets" run out.

For example, if an arena has 5 Spawn Points but 2 enemies are left alive,
the next wave will only spawn 3 enemies, but only if each of those 3 Spawn
Points have remaining tickets.

For Arena Managers:
* Set the sprite's HITAG to the spawn wave frequency, in game tics (min 90)

For Arena Spawn Points:
* Set the sprite's HITAG to the tile ID to spawn
* Set the sprite's LOTAG to the number of spawn "tickets" (min 1)

Use the palette to pair a Manager with Spawn Points to create a complete
system. A Manager can have any number of associated Spawn Points, and there
can be as many Manager systems as there are palette numbers.

Note: Spawn Points will not spawn if a player has line-of-sight with them, so
place them in non-visible locations, and try not to place other Spawn Points
within line-of-sight of each other to prevent the system from dead locking!
-----------------------------------------------------------------------------

This manager largely works by abusing EVENT_WORLD and custom statnums to reduce overhead. I am pretty proud of this effect and its elegance, and unfortunately it didn't get used as much in AWOL as I had hoped, so hopefully it gains more life in someone else's project.

This code won't run as-is, you'll need to setup gamevars and remove or fix some AWOL-specific code/vars outside the scope of this file. No support will be provided for this code.

awesome, i could use something like this in my mod

[VGames]

is there any way to keep an enemy sprite from using shade 0 while dying? I have this nice burning death effect for them that slowly darkens their sprite until its nice a blackened but when they go into their death animation, they lose the shade reduction and then when they're dead the darkened shade setting returns, For some reason I can't get them to keep that dark shade during their death animation. They're only darker when still alive and burning and when they're lying on the floor completely dead.

Make sure to apply the NOSHADE flag to the sprite before applying shade.

Is it possible to detect if the player has a given tilenumber in view? The way I was thinking of doing it was to do a hitscan check from every pixel covering the player's view, but that sounds entirely ridiculous.Still, we have some functions like ifcansee that work against actors. I probably need that but for textures.edit:Apparently this is exposed via the gotpic array in CON.ife gotpic[tilenum] 1 => means that tilenum is currently visibleThe array doesn't reset on its own (there is an EVENT_RESETGOTPICS but from what I can tell from the source code, this only gets called when handling mirrors), but you can do so manually inside your code bock:setarray gotpic[tilenum] 0So far performance seems okCredit to Mblackwell for letting me know

I'm working on a few performance related things and just want to corroborate this behavior, and I'm not sure if this is a bug in the implementation of EVENT_RESETGOTPICS or if this event is explicitly meant to function only with mirrors. Based on the description and comments in the source code, I assumed it would fire every frame after EVENT_DISPLAYROOMS, but it only seems to be fired when mirror rendering logic is happening. So if you want to reset the gotpic array independent of mirror logic, it seems to be safest to do in a DISPLAYROOMS event after all other DISPLAYROOMS events have been executed, or in any other event that runs after DISPLAYROOMS.

Interesting. So what exactly causes the elements to get set? For example, if a certain enemy dies in a place where no players are around, is its dead body tile "in view"? Or does it require that the tile is actually rendered on a screen?

Based on a quick test using the above info, sprites are rendered (or at least, inserted into the gotpic array) even if they are not explicitly on screen, based on A.) if the sprite's sector is being rendered AND B.) if the sprite is within the player's field of vision. Using the example image below, if the player were in the top left of each U, the sprite on the left room would always be rendered no matter where the player is located, as long as the player is facing in its direction, even though the walls block it from being seen. But the sprite in the right room would never be rendered until the player gets in the bottom left corner sector, at which point the sprite's sector begins to be rendered and it begins to follow those rules.



Basically, if you understand how sector rendering is performed, any sprite in a rendered sector will always be drawn if the sprite's location is within the player's field of vision, even if walls block it from being seen. One-way mask walls would presumably prevent this as they function as white walls during rendering, although I didn't test this here.

I've got these missiles that need to appear as if they're shooting out from the sides of the screen due to the position of the cannons onscreen. My problem is to get them to look like they're properly shooting out of the cannons I have to set one missile offset to 100 and the other missile offset to -100. Shooting these missiles while strafing around will cause the missile that has the offset of -100 to occasionally hit the player especially while looking up or down. I think it's mainly this missile killing the player, but it could be the other one too. Is there a way to keep these missiles from hitting the player when using these types of offsets? I've tried making them invisible when they're within a certain player distance and then showing up when they're outside of that player distance to ensure they can't hit the player, but it doesn't work. I've tried giving them the default centered offset setting and then forcing the 100 and -100 offset when they're far enough from the player that they can't hit him along with making them invisible when they're close to the player, but it doesn't work. I've also tried other offset settings like 200 and -200 or 400 and -400 but the missiles start to look off from the cannon positions as I go higher. Please help if you can.

I just tried using the htflags 2048 on the missiles when they're within a certain range of the player to make them clip through him but that didn't work either.

[jimbob]

maybe someone here can help me, i have a projectile, that when impacting a wall spawns a wall blood shooter ( using state random_wall_blood ) but the blood does not seem to shoot at the wall, could the sprite be too close? or angled the wrong way? i tried moving it on the Y axis, and rotating it 1024 units but to no avail. sometimes it does seem to shoot at random other walls so im kind of confused how the spawned sprites angle is determinded

This is one of those situations where offsets just don't cut it. You have to intervene at the instant the rockets spawn in EVENT_EGS and manually reposition the x and y coordinates. I find the rotatepoint command useful for calculating the new coordinates in these situations.

Typically when an enemy uses that state, it is facing towards the player and the back of the enemy is facing towards the wall that get bloodied. So maybe those hardcoded wall splat projectiles have a big angle offset and come out the backside of the sprite shooting them. Therefore, I would try making your projectile turn 1024 build degrees right before shooting those blood splats and deleting itself.

i already tried that, including some other angles ( 512 and others ) making the sprite spin seems to work so there is definatly a offset involved but finding the right angle seems to be rather difficult. i could always try to make increments in angle offset of about 32 units untill i hit the sweet spot.
[edit] trying to rotate the sprite didnt seem to work, there is probably something else going on in the code. so i hacked it by making a move command and using faceplayer. its a hack but it seems to work and because the move isnt instantanious it kind of splatters it allong the wall quite nicely too. its not perfect, but then again what is.

[VGames]

Ok I'm doing something wrong with the rotatepoint command.

	ifactor ID_ALT1
	{
		rotatepoint player[].posx player[].posy 100 player[].posy player[].ang temp tempb
		setsprite THISACTOR temp player[].posy player[].posz
	}

No matter what I set that 100 to the missile simply does not show up. Even if I set it to 0. What am I doing wrong? This is in the EGS event.

[VGames]

I figured it out

Is it possible to allow the player to keep and use their weapons when shrunk? I know how to disable the running hands animation when shrunk but it seems like the weapons have been temporarily removed during this shrunk state. Any way to disable this? Or is it hardcoded?
