In my game, there are things falling from the sky. When they hit the ground I want them to explode into fading colored lines or circles. I know this is possible with some particle editors out there, but they cost money and I’d rather not use them (or instead use a free one). What way would best achieve this effect? Could I make a function in my code that created these particles manually or would that be inefficient? Are there tutorials to help guide me through this process?
