My mod has a projectile that bounces off of walls and makes a trail that hurts you.
Works similar to RPG because when it shoots it autoaim the target (player).
Will bounce a few times and vanish.
Projectile will be destroyed if it hits the player.

For case of RPG you can replace the trail by the "smallsmoke trail"

Thank you, but i'd like to learn how to do it myself, and understand why this doesn't work

I'm trying to replicate the demo/security camera effect following this example from Eduke32 Wiki.

I made the special camera actor, applied the code from the wiki and it works! But there's a problem: when using the camera I still can see the weapon sprite in screen:



Also, the player is in that red X shooting the weapon (that's why it has the red palette), but I can't see the player's sprite. What could be the problem? Do I need to code something more?

The code from the example literally just moves the viewing position and does nothing else. You still have to turn off the hud display, make the player sprite visible (it is normally invisible to the player), etc.

[Perro Seco]

I managed to hide the weapon sprites, but how can I make the player visible? I thought I would have to do something with its cstat, but using DNDEBUG I see is 257. If you can give me a hint I would be very grateful.

You could try forcing over_shoulder_on to 1. Normally this would also change the camera position, but since you are already forcing a camera position as well, it might do the job. Don't forget to restore it to the previous value when camera viewing ends. EDIT: To be clear, this isn't necessary the best solution, but I don't remember what is going on with the player sprite that makes it invisible. It might be a tsprite thing.

Now i've tried a couple of things in order to achieve an rpg projectile that bounces.

//First try
defineprojectile 1660 PROJ_WORKSLIKE 32774
defineprojectile 1660 PROJ_SPAWNS EXPLOSION2
defineprojectile 1660 PROJ_VEL 1000
defineprojectile 1660 PROJ_EXTRA 300
defineprojectile 1660 PROJ_ISOUND PIPEBOMB_EXPLODE
defineprojectile 1660 PROJ_HITRADIUS 2560
defineprojectile 1660 PROJ_BOUNCES 5
defineprojectile 1660 PROJ_OFFSET 14354
defineprojectile 1660 PROJ_CLIPDIST 24
defineprojectile 1660 PROJ_TRAIL SMALLSMOKE


//Second try
//setprojectile[2605].bounces 32774
//setprojectile[2605].workslike

ofc it wont work because im missing something, but i dont see where. In the DEFS.CON ive changed "define RPG 2605" to "define RPG 1660" for the first try.

bump :')

Yeah don't do that. Leave the hardcoded RPG alone and make yours into a separate tile number. Make sure you have art on the tile you are using, too.

How does the weapon (which weapon??) know what projectile to shoot? If I wanted to make the rpg shoot rockets that bounce, how do i do it? I tried it without the change in the DEFS with no luck

You can re-declare the gamevar that controls which projectile the weapon fires:

gamevar WEAPON4_SHOOTS 1660 1

Thanks! That made me achieve ton of stuff already!
I can't get my burst project to work tho. What I want for now is just a weapon that, with a single tap on the shooting button, shoots a burst of lets say 4 shots in succession and then stops briefly inbetween bursts. I hope to get some clarification on the kickback_pic and totaltime and so. I've read the wikis but i'm missing something... Also: It seems that with this "gamevar WEAPON3_FLAGS xx" that im only adding stuff to the weapon. How do I delete the "WEAPON_RESET" on WEAPON3?

Thanks again for the help!

Last thing: Where are the weapons function defined in the first place? Not in the conf file? I've searched for RPG, WEAPON4, and flags and such, no succes..

You'll want to set WEAPON3_SHOTSPERBURST to 4, and probably add AMMOPERSHOT to WEAPON3_FLAGS.

Declaring the gamevar in your con files will erase the ones already there and only set the flags you name.

They're hardcoded into the exe.

Hmm, how do I alter the speed which the pipebomb is thrown at? I think this could be tricky to work with because there has to be a lot of hardcoding involved in those pipes I want to be able to throw the pipebomb ridicously far
And how do I add a new weapon? Like for example the expander that exchanges the shrinker when you switch to shrinker once again. I would like a secondary shotgun..

[thisbecasper]

Is it possible to make the shotgun for example shoot normally when pressing the fire button, but shoot, lets say rockets, when turnaround is pressed instead?

[Hendricks266]

Untested, but let me know how this goes.

This actually works, although it shoots 7 rockets on top of eachother. This is just a matter of redefining a couple of more things in the first bit of the code I guess. It does only fire in rpg-mode a single time when holding down the fire button, BUT, if you tap the turnaround you can spam the rockets heheh. Thank you for the reply, I learn quite a bit reading code like this :-) Maybe I can continue working on the code myself too..

Damn... Thank you so much! Works like a charm.. It even acts exactly as it should now. I just need to know why I need to do this step:

"onevent EVENT_TURNAROUND
setvar RETURN -1

- And I guess gamevar bits is used to remember last keypress, if im right?

[Hendricks266]

Setting RETURN to -1 in EVENT_TURNAROUND disables the Turn Around action from taking place.

The bits gamevar is updated with the current state of the keys at all times.

Although it doesn't work when I add the RETURN -1 bit. I guess it wont let the next onevent EVENT_TURNAROUND get executed. I think I would have to use the "bits" var like you did! But thanks for the help!

It should work. You don't need two different declarations of the same event; I wonder if that's related.

The value of RETURN is not saved; it is constantly getting set to different values by various events and such.

Hi, just tried it with my friend, and we get an out-of-sync when one of us dies. Heres the code, I hope I can make a getaround:

      quote 34
    }
    else
  	{
  		setvar choice 0
    		sound SHOTGUN_COCK
        quote 35
    	} 
    }

  	setvar WEAPON2_SHOTSPERBURST 7
    setvar WEAPON2_FIRESOUND SHOTGUN_FIRE
    setvar WEAPON2_FLAGS 1024
	}
	else

    setvar WEAPON2_FIRESOUND PISTOL_RICOCHET

}

Also the sound won't update accordingly between "weapon-switch".

[Hendricks266]

If you're using a switch style, you should update the vars directly in EVENT_TURNAROUND instead of using PRESSEDFIRE.

What is that SHOTGUNAMMO variable? I suspect you don't need it.

I think I need the var SHOTGUNAMMO inorder to keep track of current ammo of the shotgun?. Can I do it without the var and without causing an out-of-sync error? I've btw also managed to get rid of the out-of-sync thing - I still don't see the big difference between using a var like I do to keep track of the players current weapon and a call to currentweapon, which was what caused it..
