I tryed the code below but it does not run smoothly. It looks like there is a problem with friction between the two models. Here is my script; Code: action ball { var ball_move[3]; var ball_gravity; wait(1); c_setminmax(me); while(1) { ball_move.x = (key_d - key_a) * 5 * time; if(trace_hit) { ball_gravity = 0; } else { ball_gravity = -5; } c_move(me,ball_move.x,vector(0,0,ball_gravity*time),glide \| ignore_passable); wait(1); } } action platform { wait(1); c_setminmax(me); } Last edited by Toon; 06/12/09 15:06.

A usual beginner's mistake is extending the entities' bounding box all the way to its feet and then apply gravity for pressing the entity against the ground. This is not only slow due to the permanent collisions with the ground, it will also cause the entity to get stuck in any little crack in the floor, and prevent it from ascending stairs or slopes. Rather, use c_trace for keeping the entities' bounding box at a distance from the ground, and apply gravity only above that distance. See the example below for a simple movement function. http://www.puppenheim.org/ http://www.wuerfels-welt.de Old Game Tutorial: http://www.puppenheim.org/MITutorial.zip Free Game Editor: http://puppenheim.org/AlienalsWeihnachtsmann.zip http://www.puppenheim.org/blender_starting_main_settings.txt

Maybe you could try move_friction : Code: while(1) { ball_move.x = (key_d - key_a) * 5 * time; move_friction = 0; c_move(....blah..blah) wait(1); }
