Low-Level Particle System Colour Lerp
1 min
Additions
In this update I added support for multiple colours, where it lerps through them in a way similar to how unity makes blend trees. Currently they cannot have different points where it changes, however I might add that in the future. I also added particle pooling to increase optimisation, this might cause some issues in the future, however, with how I handle the pools of particles.
How it works
Since this is the smartest thing about the particle system (so far) I won’t post it in it’s entirity, but the general process is:
int index = life_percentage_rounded_down * colour_size;
float progress_in_index = life_percentage * colour_size - index;
sprite->setColours(colours.at(index) * (1 - progress_in_index) + colourse.at(index + 1) * progress_in_index);
