hey I'm making a game where the user can place blocks but those are stored inside an array list but when i add like 20 blocks the fps drops down to 8 or something?
what could i do about this or should't i be storing them in an array list?

Shouldn't happen, sounds like you're doing something very wrong. Arrays are cheap -- adding 20 objects to an array will have no impact on FPS.

If you want help, post the relevant code and more details about your process.

I'm currently not on my computer where i have the code but i have 3 arrays one for the positions 1 for the images and 1 for the polygons and i use a for loop to go through them all in the render method to render them.
i will post my code when i got home
