Hello, i'm using this code for my player movement. the problem is that the player is not able to go up stairs or to walk up ramps... is there a way to solve this? Or does anyone have a better player code [c-skript]

Hallo, ich benutze das folgende skript als player-skript. Das problem ist, dass der spieler keine rampen hochgehen kann bzw. treppenstufen überwinden kann. Kann ich dies iwie lösen? Oder hat jemand einen besseren player-code für c-skript?

function camera_move()
{
while(player)
{
camera.pan += 0.5 * ang(player.pan - camera.pan);

vec_set(camera.x,player.x);
camera.z += 40 + sin(total_ticks * 10);

mouse_mode = 0;

wait(1);
}
}


action player_move()
{
var reldist[3];
var absdist[3];
my.narrow = on;
var input_vec[3];
var Vz = 0;
var jump_able = 1;

my.invisible = on;

player = me;
camera_move();

while(me)
{
vec_set(reldist.x,nullvector);

input_vec.x = (key_w - key_s) * time * 17;
input_vec.y = (key_d - key_a) * time * -10;


my.pan -= 30 * mouse_force.x * time;
camera.pan = my.pan;
camera.tilt = min(max(ang(camera.tilt + 20 * mouse_force.y * time),-60),60);



Vz += (Vz == 0) * 70 * key_space * jump_able;

if(Vz > 0)
{
jump_able = 0;
}
Vz -= (Vz > 0);




c_move(me,input_vec,nullvector,IGNORE_ME | IGNORE_PASSABLE | USE_BOX);
c_move(me,nullvector,vector(0,0,(Vz-20) * time),IGNORE_ME | IGNORE_PASSABLE | USE_BOX);

if(trace_hit)
{
jump_able = 1;
}


wait(1);
}
}
