Your code looks correct, but I can not reproduce the problem - IGNORE_YOU works with my test projects.

Maybe the problem has some different reason, such as a wrong wall_ent pointer. Can you contact support (at) 3dgamestudio.net, and send them your project where the problem happens? They'll look into it.

7.80 was officially released meanwhile, so please post any further problems in the bug forum. I'm closing this thread.
