Hello everyone, I'm a beginner at gamemaker and am working on a tower defense type game.

My problem is when I kill about 10 spiders, I get this error:

___________________________________________
ERROR in
action number 1
of  Step Event
for object obj_turret2:

Error in code at line 3:
   direction = point_direction(x,y,object.x,object.y);
                                          ^
at position 41: Unknown variable x

Can someone look over my code and tell me what my problem is?

My game

I'm sure it's pretty simple...

is the variable "object" allways set to an instance?

This error means that game maker could not find the variable x, probably because he cant find the object "object".
replace with this:

if instance_exists(object) direction = point_direction(x,y,object.x,object.y);

thanks, that fixed my problem. I have one more question though,

I want it so if I kill 10 spiders, the spider boss will appear. So I used variables and added 1 to global.level1 ever time I killed a spider.

this is my code to make the spider boss appear..

if global.level1 = 10{
    instance_create(x,y,spider_boss)
}

My question is, how do I create only one spider boss? not many?

[borut]

if(global.level=10) and instance_count(spider_boss) <= 1{

instance_create(x,y,spider_boss);

}

if(global.level=10) and instance_count(spider_boss) <= 1{
instance_create(x,y,spider_boss);
}

thanks. I changed instance_count to instance_number and it worked perfectly!
