How do I optimize my explosion script?
I am making a 2D game where you build ships with blocks and fly them around and shoot other ships. I am making explosive projectiles for the ships to shoot, but if I shoot a missile at ship and the AOE hits >50 blocks, it creates a large lag spike. Even smaller explosion radii can lag badly.
I have tried using Physics2D.OverlapCircleAll and FindObjectsOfType (and then looping through them to get the blocks in range).
Thanks for the help!
It would probably help if you post the code, since there could be many different causes.
FindObjectsOfType is not the way to go. Iterating Collders[] should work; you should optimise this by putting the blocks in a layer and testing the OverlapCircleAll only against this layer, so you're not then having to check if everything in the array is a block.
Instantiate is expensive so if you're spawning explosions that could also be a cause; it can be better to keep them in a pool of reusable objects rather than instantiate them.
You could also use a coroutine and crunch though the array over several frames to spread the load with negligible visual impact.
