never mind I got the less than symbol and greater than symbol mixed up, but towers won't turn towards creeps correctly.

and if the new code is in creeper Creepers still spawn it self I would make a Creeper spawner with makes creepers (the creeper spawner can be an inviseble object)
Right now, Im trying to get my creeps to spawn into the world but still having no success.
Here is what I currently have:
World Stage1 Code
Creepers SuperClass Code:

By convention, method names should begin with lowercase letters. And this may be the cause of your problems, as the names of the World and Actor class methods are 'act', not 'Act'.
I changed all first letters in method names to lower case, but still need help spawning creeps into world.
nevermind fix it with my teacher.
I have another problem. I set values for objects in their constructors, how would I set those values to be used? For example, in the Creepers Class, i set a speed variable, how would I use the speed variable from the contractor to be the actual speed of the creeper? I made some attempts but when I compiled, all creepers moved at the same speed, when they all have different speed values?(Sorry if my question sounds confusing, not very good at explaining)
You have several fields in your Crreeper class that are declared 'static'. 'hp', 'speed' and 'type' are all supposed to be unique values for each creeper which would require those fields to be 'non-static'. Remove 'static' from those lines.
how would i use the values that are set in the constructors?
Well, you are shadowing the instance fields by using local variables in the constructor with the same exact names as the fields ("hp" and "speed"). To save the value of those variables in the instance fields, you need to use the following:
where 'this.hp' and 'this.speed' are the instance fields (declared on lines 19 and 20) and 'hp' and 'speed' are the variables (declared in the constructor declaration statement on line 24).
this.hp = hp; this.speed = speed;
Should they stay private or change them to public?
I posted the scenario as well on my profile.
