Sprites? Only the one that already has the costumes you want to check! Custom blocks? Just three (two are recursive)! Variables? Only the output width and height! Lists? Nada! Side-effects? ..Yeah, you'll have to put your sprite back where it was after the custom block runs :P This is a simple, portable script which gets the approximate width and height of the current costume. It essentially just scales the sprite until it just barely doesn't fill the screen, then it checks the distance from it to the four edges of the stage, and does some simple math to get the costume's dimensions! It's not perfectly accurate because it only approximates the correct size/positions, but it gets it pretty close. (Compare with the numbers in the costume editor!) It's fun to see inside and edit the current costume - you can see the script will show the new dimensions in real time as you edit! :) Feel free to use this in your own project, or make an improved version - this one doesn't try to figure out the rotation center of sprites, for example, which would be an interesting challenge, but not one relevant to why I made this. :P I'd appreciate it if you give credits with a link back to this project, but it's not required!
