This is a simple program which codes the explosion radius. This program doesn't create a simple circle of which the radius depends of the resistance of the first element touched. The program is iterative, so it's slower than a simple circle, but more precise. This program uses the color detection block to detect which material is touched and so which resistance is opposed to the explosion. That is the reason is that slow. You can change "precision" variable, to increase speed but it will makes the project less precise. /!\ The more there are explosion at the same time, the more it will be slow.
