Getting killed by friendly sentry turret's projectiles

[D2Jk]

Hello,

I'm making a sentry turret that shoots a mix of fast projectiles and small homing missiles. I've got it mostly worked out, but the only problem remaining is that the said projectiles can kill the player who gets in their way. :)

The sentry turret of course has +FRIENDLY propery set already. +DONTHURTSHOOTER doesn't really work here because it would only protect the turret itself, not the player.

Any ideas?

A missile with this flag passes through actors of the same species as the actor that shot it, if any.


With this, make the player the same species as the turret, or vice versa.

Brilliant, thank you.

On MBF, the FRIEND flag makes them try their best to avoid shooting through you. Maybe it can be implemented in the ZDoom engine too? It's more realistic than projectiles which "ghostily" travel through you.

You might be able to do something with the recently added A_CheckLOF.

For now I'm ok with the current implementation, but I will take a look at these suggestions. I'm thinking it might prove too complicated to improve this further, though. Since the shot projectiles do not travel instantaneously, it would be possible to step in front of them just after the line of fire check.

By the way, I was also wondering if it's possible to make a projectile that momentarily reduces the movement speed of hit monsters? I assume it's not possible, and the ice or freeze related functions and properties are probably just used for some weapon effects in some game other than Doom (Hexen?).

yes, you can make a projectile reduce thes speed of an actor, but you need to mess with the actor properties using the decorate lump. this wad have a good example of slowing projectiles http://www.doomworld.com/vb/wads-mods/60969-beyond-reality-its-finished-try-it-today/
