Hey, I'm stuck again. This time it's something to do with my objective. It's one of those Undefined is not a field object, and it's something to do with my BMP.

objective_add(1, "active", &"DEFEND_OBJ1",obj1.origin);

the BMP's targetname is obj1

Here is the entire script

it would help us more if u provided us with the actual error. as we might be able to solve this faster now that u have script up.

I believe your code should work like this:

objective_add(1, "active", &"DEFEND_OBJ1",getent("obj1", "targetname").origin);

You seee when you put just OBJ1 the game doesnt know what that is, hence the UNDEFINED error, you have to tell it what it is.

it seems ok and right. probably u need to compile the bsp as u might have added that and forgot to update the bsp in the process.
