This explanation of the problem was correct - it seems he just forgot to write it in the code.

Change the line

player_movedist[2] = player_z_speed;
to
player_movedist[2] = player_z_speed*time_step;
(= multiply speed with time)

Result:

player_z_speed=15*time_frame; //Player jumps much higher at low framerate. Same as in the beginning

-------------------------

player_z_speed=5; //Player jumps lower at low framerate. It`s strange.

@xxxxxxx: You can't change BBOX manually without setting it's FAT and NARROW!
@Rondidon: I can send you a framerate independent movement with jumping if you need me to, just send me PM.
About BBOX (TESTED):
Have no idea (and no time to check) about framerate problem you have, but as I said, can send working one.

Do you tryed it? c_setminmax set FAT and NARROW!

xxxxxxx

It`s maybe stange, but with this values the code is 98% framerate independant. Same jump hight at 5FPS and 80FPS. Maybe the Acknex engine confuses the time_frame and time_step variables in huge projects with many simultan functions and many entities? Hm.

player_movevector[2]=4+4*time_frame;

@3Run I try to get my own to work without bugs. But if I really get stuck anywhere, I`ll PM you Thanks.

@xxxxxxx Yes and it seems to work. Thanks very much. I forgot to set those flags when I tried to setup the collision box manually like 3Run said.

Thank you very much. I really appreciate your help!

I thought that "player_movedist[2] = player_z_speed*time_step;" would be precise enough. Obviously not - it does not take into account the decreasing speed within time_step. So the precise formula would be:

player_movedist[2] = player_z_speed*time_step - gravitation*time_step*time_step/2;

and set player_z_speed to a value independend of time_step.
