z-height of projectile when hitting wall?

In ZDoom, I suppose?

https://zdoom.org/wiki/Projectile

As you can see, if you provide XDeath and Crash states to your projectiles, it'll only enter its Death state when hitting a wall. Then you can put your script that queries its Z height in its Death state sequence.

I don't really need it to hit a wall when an enemy is standing before it. This case can be ignored.

But I also do not know how to add states to actors... or how to access attributes of said projectile when hitting the wall.

something like this

            TNT1 A 0 ACS_ExecuteWithResult(994,0,0,0,0) //script to return z position of projectile

            MISL C 6 Bright

            MISL D 4 Bright

            Stop
        XDeath:

            MISL B 8 Bright A_Explode

            MISL C 6 Bright

            MISL D 4 Bright

            Stop
        Crash:

            MISL B 8 Bright A_Explode

            MISL C 6 Bright

            MISL D 4 Bright

            Stop
    }
}

 

 

This is almost exactly what I need. The only thing missing is my understanding of how to pass Z into ACS_ExecuteWithResult as parameter (self.z or something similar?).

I recreated a destructible column that I once saw in a clip (unfortunately, I didn't bookmark it and can't find it again).

With the Z coordinate of the projectile impact, the script could be upgraded.

DESTRUCTIBLE COLUMN

pass z as one of your script args

eg:

ACS_ExecuteWithResult(994,z,0,0,0)

script 994 (int z_pos)
{
//do stuff with z_pos here
}
