Hi, i have 2 variables: player_speed.x and player_speed.y
How can i limit these variables ? They should not going over a specific value .For example 100 (and -100 for the negativ movement). Any ideas ?

Try this:
player_speed.x = minv(100,(maxv(player_speed.x, -100))) // player_speed.x will be limited between -100 and 100

player_speed.y = minv(100,(maxv(player_speed.y, -100))) // player_speed.y will be limited between -100 and 100

player_speed.x = clamp(player_speed.x, -100, 100);
player_speed.y = clamp(player_speed.y, -100, 100);

This two codes are working but my player is moving a bit in the wrong direction now. Really weird...I'll try to fix this, any idea is welcome

btw I move my player ( a ball) with this code:
phent_addtorqueglobal (ball, player_speed);

Than use this:

or

Hmmm, it says error:

"Can not convert `struct VECTOR` to `Fixed`
player_speed = clamp(player_speed, -100, 100);

"Can not convert `Fixed` to `struct VECTOR`
player_speed = clamp(player_speed, -100, 100);


My, player_speed is a vector, maybe this is the problem ?

post your code, it's easier to highlight the problem

You use physics,add this to the code:

phent_setdamping(ball_entity,70,70);

Here the action of my player:

action spieler()
{
zeiger = my;
my.emask |= (ENABLE_BLOCK | ENABLE_ENTITY);
phent_settype (zeiger, PH_RIGID, PH_SPHERE);
phent_setmass (zeiger, 1,PH_SPHERE);
phent_setfriction (zeiger, 500);
phent_setdamping (zeiger, 10, 50);
phent_setelasticity (zeiger, 50, 100);


while (1)
{
jump.x = 0; jump.y = 0; jump.z = 30000;
my.event = jump2;
winkel = cam_angle + 270;
if(key_cur)
cam_angle -= 3*time_step;
if(key_cul)
cam_angle += 3*time_step;

if(key_cuu)
{
player_speed.x -= cos (winkel) * 3 *time_step;
player_speed.y -= sin (winkel) * 3 *time_step;
}

if(key_cud)
{
player_speed.x += cos (winkel) * 3 *time_step;
player_speed.y += sin (winkel) * 3 *time_step;
}

if(key_cud != 1 && key_cuu != 1)
{
player_speed.x = 0;
player_speed.y = 0;
}
cam();
phent_addtorqueglobal (zeiger, player_speed);
wait (1);
}
}


player_speed is a vector (i have written VECTOR player_speed; in my Code). As you can see i always have used phent_setdamping, that doesn't help.

if(key_cuu)&&(player_speed.x > -100)
{
player_speed.x -= cos (winkel) * 3 *time_step;
player_speed.y -= sin (winkel) * 3 *time_step;
}

if(key_cud)&&(player_speed.x < 100)
{
player_speed.x += cos (winkel) * 3 *time_step;
player_speed.y += sin (winkel) * 3 *time_step;
}
