I was testing my map and the zombies wouldn't move when previously they did. I moved the spawns a little bit to see if they'll move again. After I compiled and launched it, I got an error message from seemingly nowhere. I think the error is: ERROR missing images "givewarm_zom_dempsey_device.iwd"
ERROR missing images "viewarm_zom_dempsey_n.iwd"
ERROR missing images "viewarm_zom_dempsey_device_n.iwd"
ERROR missing images "givewarm_zom_dempsey_c.iwd"

missing images and bad syntax are two different things. should be able to still play with missing images, just wont be visible in the map

Is there a crash log in the codwaw directory that I can copy into here? If not, is it possible to copy the console?

launch map after typing "logfile 1" into console

After typing in logfile 1, it gave me a different error having to do with my zombie counter script. I fixed that but now I have another question, why don't my zombies move when they spawn? I have already checked the KVPs, the zones, and the path nodes.

you probabbly have kvps wrong, if they need to walk directly to the player you need script_noteworthy find_flesh on the spawn point ent. if not make sure they can reach the barrier with the path nodes

The KVPs are good and most of the zombies are risers. The barrier zombies don't work either.

Make sure your KVPs are as follows:

ZOMBIE KVPS:

targetname = zone_name_spawners
spawnflags = 3
script_forcespawn = 1
script_noteworthy = zombie_spawner
count = 9999
script_string = riser

SCRIPT STRUCT KVPS FOR RISER:

targetname = zone_name_spawners_rise
script_noteworthy = find_flesh
script_string = riser

Make sure that your script structs for your risers are half-way through the ground. Make sure pathnodes don't collide with any other models.

I fixed it, the problem was overlapping path nodes
