How do you make a BFG9000 hurt stuff around it?

[BLACKWIDOW]

Example from Complex Doom:


I want to make it so it the BFG Ball hurts stuff around it just like in Doom 3

I really need help on this and i clearly don't understand how to make it like that.

I don't know myself, but you could study how Argent does it: viewtopic.php?f=43&t=52363

I can actually help! D4T has this already, so please, download it and open up the bfg's decorate.

Look for BFGLooker

The way it's done there is that there is are seeker actors that are spawned and they are spawned at an angle AND have a 60 degree FieldOfView, while also being spaced 60 degrees. So each of these is responsible for a certain angle judging from the ball's perspective!

Study that case in detail, you'll realize everything quickly

For the most basic function, you give the projectile +ISMONSTER, +FRIENDLY and then use A_LookEx to make it find targets and some sort of an attack function to attack them. It works like a monster but looks like a projectile.

It can be done in different ways and D4D probably does it better.
