That looks pretty nice, I wish I knew how to do that

Alright guys final update on the mapping animation because I'm trying to document what I did a bit for future use. I used the "python-fu" console to implement a python script which does all of the math given some starting positions and angles for the objects and creates the paths for however many frames you'd like. I'll probably find a way to implement variable velocity/acceleration on the objects dependent on their angles in the future. I could adapt the code for any number of patterns and objects too! This one was pretty easy to create the functions for since there were just three circular paths. The functions themselves are pretty self explanatory if you know trig, but feel free to ask me any questions if you're so inclined.

Probably the biggest issue was figuring out how to get the numpy package linked in GIMP. Here is a link to the post which solved my problems after a while of getting nowhere. Hopefully that link never dies, but just in case I've saved the image within it.

Second biggest issue was with how python within GIMP was handling the numpy arrays and how float-int math was being done. It seems that between versions of python, float-int math is pretty inconsistent, so I got fed up with looking at documentation and just made everything a float until I needed to use a number for indexing. I also rounded to ints when I told GIMP where to draw, but that was unnecessary. The way I've indexed the numpy arrays in the script seem to work, but they were inconsistent from compiler to compiler.

I could improve the script by containing all patterns (in this case circles) within one array, having the number of columns equal to double the amount of objects (to include both x and y coordinates for each object), or include a third dimension for the number of objects. Then I'd just have to use some nested for loops instead of a lot of the copying and pasting I've done in the current code. I'll probably also update the script to create the desired number of layers and name them so you can just open up GIMP, create a new project, run the script, and be done.

Aaaaanyways, here's the python script in its current state:

pdb.gimp_context_set_brush_size(30)
counter = numFrames

for layer in image.layers:
    counter -= 1
    x = int(round(coordsT_Lead[counter][0]))
    y = int(round(coordsT_Lead[counter][1]))
    pdb.gimp_pencil(layer,2,(x,y))
    x = int(round(coordsT_Lag[counter][0]))
    y = int(round(coordsT_Lag[counter][1]))
    pdb.gimp_pencil(layer,2,(x,y))

    x = int(round(coordsBR_Lag[counter][0]))
    y = int(round(coordsBR_Lag[counter][1]))
    pdb.gimp_pencil(layer,2,(x,y))

And below are some of the animations it produced. All have 15ms between frames, as it seems that's the lowest that Chrome will support. That's 66.67 fps, which is good enough for me. Each animation's number indicates how many frames make up a full loop.

Cause i don't have a good pc and it runs perfectly. Look, this is the game (it's better than it seems)
