no doubt in the game tank rock can crash zombies.
to control spit acid damages, you should need [L4D2] Spitter Acid Damage by Silvers.
or set *_rand to 27 (this mean 31 - 4), make spit acid wont appear

That is so funny to see rock coming from grenade launcher, great job

thanks report, looks some grenade_launcher_projectile didnt have owner, anyway double check it

You still have to check if entity is valid in SDKHook_SpawnPost.

PHP Code:


SDKHook(entity, SDKHook_SpawnPost, OnProjectileCreated);

void OnProjectileCreated(int entity) {

    if ( entity <= MaxClients || !IsValidEntity(entity) ) return;

    ...
} 


Better use EntIndexToEntRef if using RequestFrame, entity could be removed or invalid on next frame.

PHP Code:

RequestFrame(ReplaceProjectileVVel, EntIndexToEntRef(entity));

void ReplaceProjectileVVel(int entity)
{
    if( (entity = EntRefToEntIndex(entity)) != INVALID_ENT_REFERENCE )
    {
        .....
    }
} 


[NoroHime]

alright, but why we need check projectile isnt client?
anyway patched it, just in case if someone kill the projectile entity on OnEntityCreated()

update

v1.0.2 doubled the double check, for safe; 4-November-2022(3rd time)
