Hey I was wondering how exactly the spawners work in Black ops 3 and how I can make it so a player uses a trigger that causes a lot of zombies to spawn. I was able to do this back in WaW by placing zombie spawners that would spawn one zombie and turning them on through script. You don't use spawners in Black Ops 3 though (except for placing one in the map), as everything is done through script_struct risers. Does anyone know how these spawners work, and how they can be triggered through script?

You can still spawn in a zombie at will, spawn_zombie in zombie_utility.gsc, where you want, from a spawner, moving the zombie to the point you want them to spawn at, using ForceTeleport like you'll find in the scripts. Increasing the zombie total var and so on will prevent it from counting towards the normal spawned zombie count.

You can still spawn in a zombie at will, spawn_zombie in zombie_utility.gsc, where you want, from a spawner, moving the zombie to the point you want them to spawn at

So I found the function you were talking about in zombie_utility, that looks like:

function spawn_zombie( spawner , target_name , spawn_point , round_number)

My question is, when I execute the function in code what do I put for "spawner" and "spawn_point"? "target_name" seems to be the targetname of the given spawner, but what do I put for the others? Also I assume I don't need to include round number for this function to work cause of:

if(IsDefined(spawn_point) && IsDefined(level.move_spawn_func))
			{
				guy thread [[level.move_spawn_func]](spawn_point);
			}	

All you need to spawn a zombie is to get the spawner and then ai = spawn_zombie(spawner); target_name simply asigns the targetname if it is defined. spawn_point, if defined will run the pointer function in level.move_spawn_func, which is move_zombie_spawn_location, and spawn_point should be a struct. I haven't seen the point in round_number or _starting_round_number which it is assigned as.

ofc, if you just use ai = spawn_zombie(spawner); you may need to do other things manually on ai such as forceteleport to where you want, so maybe try ai = spawn_zombie(spawner, spawner.targetname,spot); Make spot a struct, either by spawn or get it in your map somewhere. You can even just try spot = array::random( level.zm_loc_types[ "zombie_location" ] );

theres nothing "different" about how bo3 does things...

waw also used riser structs - they both require at least one spawner to work

if you want multiple spawning zombies that are not rising - then you copy paste the spawner
