I have made a top-down shooter game with lots of enemies moving towards to the player. I have been thinking what would be a good solution to handle all those enemies without much performance issues.
Each enemy has a movement script with Update function to handle all the movements.
An enemy manager script with Update function to iterate the enemies to make them all move.
If you’re experiencing performance issues try identifying the code that’s causing said issues using the profiler. Otherwise, if everything is running smoothly and working then I don’t see what the problem is. Now I did google this because I am curious, say you have thousands of objects moving, here’s an answer from a forum post I found interesting:
Don’t put a script on each thing. Instead, have one script that moves all of them. That’ll save you some overhead when you’re moving this many things.
Move all of those objects to the top of the hierarchy. Moving things that have parents are slightly more expensive.
Reduce the number of if-statements
Instead of the moving-bool, have things that are not moving in their own list, which you don’t do anything with.
Instead of having a reverse bool, change the value of your destination when you get to the current destination.
