At the moment, it moves the sprite forward, then back to start point and stop there. What do I need to do for making an endless loop for this? Code: while(1) { enemy_pan1.pos_x += speed_x; if (enemy_pan1.pos_x >= 500) { enemy_pan1.pos_x = 500; while(1) { enemy_pan1.pos_x -= speed_x; if (enemy_pan1.pos_x <= 300) { enemy_pan1.pos_x = 300; } wait(1); } } wait(1); }

Code: while(1) { enemy_pan1.pos_x = minv(enemy_pan1.pos_x + speed_x, 500); while(enemy_pan1.pos_x != 300) { enemy_pan1.pos_x = maxv(enemy_pan1.pos_x - speed_x, 300); wait(1); } wait(1); } just to stop the extra movement below 300 and above 500
