I thought maybe it wouldn't work quite right but that's actually pretty much perfect. D'oh.

Another tidbit I'm having trouble figuring out. The blood flies through the air, and when it hits something it spawns a bloodsplat. This looks good when it hits the ground, rather natural and the like. I can't figure out how to setup so that when it hits a wall, instead of spawning a bloodsplat it shoots BLOODSPLAT# along the walls. I can't really figure it out. There is no ifnearactor equivalent for walls, as far as I know. Any ideas?

First, do not set the projectile to spawn anything (set spawns to -1)

onevent EVENT_KILLIT

ifactor MYBLOODPROJECTILE
{
  getactor[THISACTOR].htmovflag TEMP
  ifvarn TEMP 0 // this means it hit SOMETHING, maybe a wall, maybe a sprite
	  state random_wall_jibs // if there's a wall nearby, it will splatter the wall
  else iffloordistl 8
	  spawn MYBLOODSPLAT // if it didn't hit something and it's near the floor, spawn the floor splat
  setvar RETURN 0
}
endevent

I just typed this and didn't test it.

No dice. =(

Thanks, DT. I've figured it out. For future reference, the angle wouldn't let the hitscan register I don't think. I had to subtract 960 from the angle to get it to work.

What are the ways to increase the clipdist of a projectile other than defining it in the defineprojectile part? In my case, one of the monsters shoots fireballs at the player, but they don't hit him, and just go through. I've increased the clipdist to 160 but nothing happens... (The projectile isn't even that big at all, it's a png, so I used the setuptile command to buff it's size up, maybe that's the problem. But, it's size is meant to be big) Any advice?

The problem isn't clipdist. The problem is that the dimensions of the tile that you have defined as the projectile are too large. I know it sounds strange, but trust me, there is an engine bug which makes large projectiles not hit the player. I've had to deal with it many times and it sucks. If you are using setuptile or dummytile, keep the dimensions down to like 16x16 to be safe. It's fine to use sizeat (or scale in the case of a model) to make it bigger in game, but the tile dimensions must be small.

Oh didn't know that. Thanks for response.

Eitherway, I think the maximum clipdist value must be increased. (In case of a very very big projectile, or a monster)

You have a monster or projectile that needs more than 255 clipdist?

Tribomb control

5 laser/tribomb angle
6 1: delay, 3:armed
7 Activate tribomb when T7 reach 0

This is from the "htg_t" article. How do you use htg_t for tripbomb control? I replaced it with a grenade launcher and when I fire, player halts for a very small second and then continues to move. I thought this could be from 1:Delay and would be fixed if I had turned it to 3:armed.

I'm having great difficulty in trying to do something simple.
I want a projectile to obtain the ID of who spawned it then have the projectile change its stats (damage / speed / size etc...) from collected gamevars from the spawner.

Firstly I can't seem to be able to make it know who spawned it and used a stupid method of findnearactor as a temp measure.
Secondly I can't get the projectile to change its stats, they are always the same. I.E: "setthisprojectile[THISACTOR].extra 50" does 2 damage which is what the projectile was defined at. Basically I don't appear to be able to override the default values allready defined.


I thought this was going to be easy and the thing I did this morning would be hard but it turned out to be the complete opposite for both.
Oh and I tried all my adjustments through event_egs. If I'm not meant to do it through there then how do I get my actor to obtain the ID of the projectile that it spawned?

[Jimmy]

You could try using "getthisactor[THISACTOR].owner TEMP" in like EVENT_EGS or EVENT_GAME, and it should give you all the information you need.

[XThX2]

You could do that in the actor code anyway, type

getactor[RETURN].owner TEMP

by using the eshoot command. The owner will give you the ID of the sprite which spawned it, so you can refer to the owner like

getactor[TEMP].bla blabla

or anything like that.

To your second issue, I had the same problem too, couldn't figure out anything simple for that though. I ended up adding extra damage in actor code of every monster if got hit by that special projectile. (Refer to Dr. Kylstein or James' solution they gave you for adding up damage)

I didn't think the actor structure stuff works on projectiles hense why they had their own member structures but that has sovled part 1 of my problem.
Part 2 is having the projectile change its stats but if the actor member structure worked above then I guess I can use that here too?
I'm just going to do some testing now.

[Chip]

OK, it all worked!
So basically the getactor stuff worked better on projectiles then the getthisprojectile stuff.
setactor[THISACTOR].extra 50 worked in over riding the damage and now that I can have it obtain the spawner's ID I can therefore make changing damage amounts based on the actor using it (despite being the same actor sprite - this is my leveling system at work again)

getactor[RETURN].owner TEMP

That may come in handy later on.


Thanks guys.

Yeah, I have also noticed that get/set thisprojectile doesn't always work. That is to be expected if you are dealing with one of the old projectiles like RPG, but IIRC it is a problem with custom projectiles as well.

I can happily report that I've never messed with that stuff before, thereby getting me off the hook.

What's the maximum amount of sound files you can define in defs.con and user.con?

[Spiker]

Noobish question: How can I increase the number of displayed frames for explosion from 21 to 24 I know this question may be obvious for you but I'm serious

[XThX2]

action EXPLOSION (I don't know if this is the correct one) x y z t e

x = How many frames should be skipped from the actor's define number.
y = Amount of frames.
z = Amount of angles.
t = I think this takes either 1 or -1 which are normal and inverse.
e = Action Time.

The max sound limit's 2560.

Look up rotatesprite in the EDuke32 wiki to understand this better. Replace the names I put in there (such as "tilenumber") either with numbers or your own variables. Good luck.

hmmm no luck I tried different variables countless times... what would be the demensions & coordinates if I wanted to just display a sprite dead center in the screen during HEAT_ON?

This code prints the messages at top of my post. Why does it do that? (Walls?)

[Danukem]

Because the value of TEMP was -16382, and valid sprite IDs are between 0 and 16383.

Is it possible to make a projectile go through actors ? (One way I thought would be to make it a normal actor and have this in it's code, but I want to keep it as a projectile on it's own)

	getactor[THISACTOR].cstat cst
	ifvarand cst 1
	{
		xorvar cst 1
		setactor[THISACTOR].cstat cst
	}

That's the wrong cstat bit. The one you want is 256. Other than changing cstat on the sprites, I don't know how you could prevent a projectile from hitting them.

[XThX2]

Oh that explains why my actors were blocking... Thanks!

[XThX2]

How can I identify if an actor hit the wall or a sprite by htmovflag? I realized the bug errors given to me by the invalid sprite number is definitely because of hitting walls, and I need the code to not execute when that happens. To explain what I'm doing with htmovflag, I'm using it to deal damage to what it hit and spawn it's explosion frame. (The actor in question is a projectile with no defineprojectile)
