Make a projectile not explode when hitting an enemy

[adasiok]

Hello,

I'm working on an RG14 Hand Grenade lately and came to a problem, how can i make the grenade not explode immediately after hitting the enemy but rather bounce off it and explode after a short amount of time?

Sending a projectile to its death state on collision is hardcoded behavior of the Doom engine. ZDoom allows you to choose however a different state depending on what the projectile collided with, so you could define this bounce, wait, and explode behavior in the XDeath and Crash states. If you're not targeting ZDoom, it is going to be more difficult. You could contrive to let the grenade die normally but spawn another (technically different) grenade that will fall down, wait, and explode; this should be doable with MBF21 and perhaps even with just plain DEHACKED depending on what you can sacrifice for the effect.

You might want some bouncing happening with the appropriate flags, in you case, you need ALLOWBOUNCEONACTORS and of course BOUNCEONACTORS other than just the BounceType property

If you're using DECORATE, you'll want to get rid of the "PROJECTILE" flag.  That is a collection of other flags, some which cause the projectile to jump to its "Death" state when it collides with walls/floors.

Take a look at the PROJECTILE flag in the ZDOOM wiki so you know what you know exactly what it does, and what you may need to add if PROJECTILE is removed.

Mentioning your target compatibility is probably a good idea. For dehacked, this behavior is possible starting with MBF.

Oh, sorry, I forgot to mention it. I'm using GZDoom
