Another feature was added to this tool to help the artists make wall assets for the game, but it also doubles as another option for therapists to create wall poses. The UI grid can intake an image file (a 2D sprite) and output a grid based on the alpha values of individual pixels from this input image. This initially always looked at every pixel, but to help the tool deal with higher resolution (or just larger) images, I also added a resolution factor that would just very simply look at “every x pixels” instead of each individual one. The resolution factor just gets multiplied into the loop looking for pixels.
For example: With resolution factor of 4, the tool will look at pixel numbers: 0 * 4 = 0, 1 * 4 = 4, 2 * 4 = 8, etc.
While this clearly isn’t an amazingly intelligent system, it is a simple way to generally get a roughly similar shape to initially higher resolution images without creating hundreds of thousands of objects.
