I have one game on one screen/device. I have 4 players in it. I want to assign a small button on 4 corners of the screen. Then as each player touches each side and the more each one clicks, the more the player will move. But I want each touch to move only a small step. This way they would have to continuously tap tap to keep moving.
It is like a racing game where 4 players can play. I made the players and the screen, but do not know how to do the moving part as I described.
