V_Sola OP Newbie V Joined: Nov 2007 Posts: 13 Germany / Munich	Hi, i wrote a code in which i used a Pointer that should tell my player-model to move on w ENTITY* robot; function move_ahead() { robot.x += 5; } function main() { video_switch (8,32,1); level_load ("Drohne_Level.wmb"); on_w = move_ahead; } action Drohne() { robot = me; } , but after i had started the programm evertime i pressed the engine only told me theres an empty Pointer. Does anyone know what's my mistake? Thanks in advance, v_sola.

Update to A7.66, Then try this: Code: #include <acknex.h> function move_ahead() { robot.x += 5; } function main() { video_switch (8,32,1); level_load ("Drohne_Level.wmb"); on_w = move_ahead; } action Drohne() { robot = my; }
