You don’t even have to sort the list of enemies. For each tower, walk through the list of all enemies (using a for loop), keeping track of the “closest enemy so far” and how far away from the tower they are. When you get to the end of the list, you know “closest so far” is actually the closest, peri...

Honestly don’t worry about performance at first, there re ways to make collision checking faster later (using some kind of spatial partitioning data structure for everything your player could collide with). Having blocks that each have their own dimensions and a position that isn’t necessarily snapp...

If you’re hung up on efficiency, hence having trouble choking from your 10 ideas, try not to worry about it!

If that’s not possible, implement Bobbie68’s idea as a ring buffer.

I don’t k is what anim8 is, but it expects its first parameter to be a positive integer and you aren’t passing anything.

Is this all of the code? If not then you need to provide everything you’ve written. Right now I don’t see self.x and self.y being set anywhere.

Also, for context, what, if any, programming background do you have?

I don’t know that love is packaged in a way to make that easy, but presumably you could download the source use the C++ directly instead of going through the Lia interface.

But you might be better off using a different cross platform library, like SDL2.

Actually, I could do with some help for it - currently the lighting is very smooth, and I'd rather it's pixellated and alligned with the texture, which could help with optimising if its at it's native resolution, however short of rendering each texture to a canvas every frame, I can't think of a go...
