I am trying to create a function that will say "if object.x == -10" then " life = life - 1" How can I do this?

Collisions
Like this?
1 2 3 4 5 6 7 | function hitBadStuff(obj) if obj.x <= -10 then life = life -1 end end hidBadStuff(obj) |
I've got a routine that will calculate the exact distance between two objects regardless of the angle between them which is better if you're not restricting your movement to just the x axis.
One thing that you need to know is the size of your objects.
1 2 3 4 5 | local xdist=obj1.x-obj2.x local ydist=obj1.y-obj2.y if ((xdist*xdist)+(ydist*ydist)) <= 20 then -- Check for collision. life = life -1 -- decrease life end |
