I'd like for some text to appear on screen when shooting a zombie with 1 bullet. Any easy way to do this?

this will put text on screen every time you shoot a zombie:

step1) put  a copy of _zombiemode_spawner in your root/mods/mapname/maps folder if you dont already have one there

step2) open _zombiemode_spawner in your root/mods/mapname/maps folder and add

self thread text_on_hit();

under

self thread zombie_think(); 
self thread zombie_gib_on_damage(); 
self thread zombie_damage_failsafe();

so now it should look like this:

self thread zombie_think(); 
self thread zombie_gib_on_damage(); 
self thread zombie_damage_failsafe();
self thread text_on_hit();

step 3)  at the very bottom of _zombiemode_spawner paste this:

text_on_hit()
{
	while( 1 )
	{
		self waittill( "damage");
		iprintln("YOUR TEXT HERE");
	}
}

save the changes you've just made

step 4) in launcher go to the mod builder tab make sure the _zombiemode_spawner box is checked, then rebuild your mod.ff and IWD file.

That's all.

Thanks! I've modified it a bit, and it works great.
