Hello there, im making a snake game to get familiar with C3. The game is a snake game without the grid system. If you touch the left part of the screen the snake turns left and the same with right. But i have a problem. I want the snake to turn left if i touch the left side and the snake is facing up at the time of pressing. then its supposed to turn that way until i releas my finger. And if the snake looks down at the time of pressing its supossed to turn to left also. How do i do that? i hope you understood what i meant. thanks
