To use this it is very simple make a variable named selected and make it for every sprite you you want one tap. Do you know when you make a project and you hold mouse down and the numbers go up very fast well this project makes all things one tap.
A rather simple project that I made go into code to see how! Yes this is simple and now for even more simpler use just use this sprite clicked and wait until not mouse down and touching mouse pointer. If needed please some credit
