Particles!

[ACBob]

Somehow I'd completely forgotten I have some stub code for a particle system.\ Always facing the camera, in a mock-modifier setup like Source:tm:.

Particle definitions handled by TOML, the code just knows when to use them;

[block.break]
# for regular particles (see explosion), there'd be a tex variable. It doesn't matter here as it is set by code.
# Also omitted: texatlas, texdiv, texatlasrand
num=125 # 5 * 5 * 5
explode=[-5,-5,-5, 5,5,5] # As a first go, launch immediately from X,Y,Z to X,Y,Z
linear=[0.0,-9.8,0.0]# Apply linearly every frame (multiplied by delta), One set of X,Y,Z means no random
collision=true

[explosion]
tex="explosion.png"
# [ [X,Y, SX, SY] ], If multiple it randomly chooses.
texatlas=[[0,0, 2,2], [0,2, 2,2], [0,2, 2,2], [2,2, 2,2]]
texdiv=8 # How many textures there are in the atlas
texatlasrand=false # If true, the U/V Is then randomised in the atlas chunk
explode=[-2,-2,-2, 2,3,2]
linear=[0.0,3.25,0.0]
collision=false

Animated textures should be considered. Would you then specify an "animated" attribute where it would treat multiple atlas indices as frames?

as of 47b3b22aba5ca07e2e2ec21e00d50d16ed21269a particles are implemented but are lacking the toml representation

As good as it needs to be for alpha 1
