I'm trying to make a new enemy for my next map, but however I'm having a bit of a problem with it. I wanted him to fire two missiles but it looks like he fires both on top of each other. I did looked up on the eduke wiki, and i did found an answer there but I still have problems though.

Here's the code that I have

        sound RPG_SHOOT
        setprojectile[RPG].offset 224
        eshoot RPG
        setprojectile[RPG].offset 14354

        setprojectile[RPG].offset 14578
        eshoot RPG
        setprojectile[RPG].offset 14354

But when actually playing, this happens


It looks like it doesn't work. I've even set the second one at -224 once too, it still doesn't work.

Also checking the eduke log this is what it says

Line 5884, setprojectile: VM_SetProjectile: no projectile defined for tile 2605
Line 5886, setprojectile: VM_SetProjectile: no projectile defined for tile 2605
Line 5888, setprojectile: VM_SetProjectile: no projectile defined for tile 2605
Line 5890, setprojectile: VM_SetProjectile: no projectile defined for tile 2605

Does this mean that it's incompatible with the original missile, or am I doing something wrong.

In general, setprojectile is designed to work on custom projectiles that you have defined yourself. It does not reliably work on hardcoded projectiles such as RPG.

[Jolteon]

It doesn't? Rats. Well I guess there was no shame in asking. Thank you for clearing that up for me.

The easiest solution in this case is to move the actor over in between shots, then return the actor to its original position. This will ensure that the RPG fires from a different position, and still aims correctly at the player. I have code for doing just that.

If it's ok to ask, how do you do that?

[Daedolon]

Create an actor pivoting around the firing actor, and have that spawn the things.

[Danukem]

// declare the following vars wherever you do that in your mod:
gamevar x 0 0
gamevar angvar 0 0
gamevar savx 0 0
gamevar savy 0 0
gamevar newx 0 0
gamevar newy 0 0

// in the shooting part of the code, do this:
shoot RPG
geta[].x x
geta[].ang angvar
sub angvar 512
add x 384
rotatepoint sprite[].x sprite[].y x sprite[].y angvar newx newy
geta[].x savx
geta[].y savy
setsprite THISACTOR newx newy sprite[].z
shoot RPG
setsprite THISACTOR savx savy sprite[].z

If the position on the second RPG shot is wrong, change sub angvar to add angvar. You can also play with the distance 384 to make it smaller or larger (that one is the gap between the shots)

[Jolteon]

After messing with the distance a bit, It actually works. Thank you Trooper Dan.



Couldn't get a good screenshot though.

(Also thank you too Daedolon for trying to help as well.)

I also want to thank Dan for the code. I found it useful to make enemies shoot projectiles from left/right rather than the center:
