I tryed to use the aum 88 to make a playercar code.
But with a physical car;

And here is the player code

while (players_health > 0)
{

wait(1);
}

while (player_in_car == 1)
{
wait (1);
}

_______________________________________________________________

The problem is that I can controle the player with no problem but when im neer the car and press the space butten, nothing happens.

Doese somebody know what I did wrong?
thanks furthermore.

Oh I almost forgot.
It must be something wrong in code becuse the playercar projeckt form the aum (88) worked perfecktly.

Hmm, did I ask wrong or bad?

while (players_health > 0)
{
pl_move();
pl_camera();
wait(1);
}

// shouldn't the following lines be in your while loop ?

if ((vec_dist (player.x, car.x) < 100) && (key_space))
{
while (key_space) {wait (1);}
set (player, PASSABLE);
player_in_car = 1;
}
while (player_in_car == 1)
{
wait (1);
}
}
