I want to create an educational app where kids can learn to write alphabets.
I want user to trace with finger over the alphabet. when user drag finger. it fills up the empty image with a color. color shouldn’t go beyond the fill area.
i am thinking of using DrawNode, but i need different width fill. also draw shouldn’t fill outside the alphabet.
Any suggestion which technique is best and how to do it. i am doing this in cocos2d-x 3.16 c++.
