GameMaker [SOLVED]keep same direction when colliding with wall

[FoufaDjo]

when the object move to the left and collide with the wall he stop moving but change is direction to 0 how can i fix that
spdmax = 2;
accel = 0.5;
friction = 0.3;
if rkey hspeed += accel;
if lkey hspeed -= accel;
if dkey vspeed += accel;
if ukey vspeed -= accel;
speed = clamp(speed,-spdmax,spdmax);
if (place_meeting(x+hspeed, y, osolidobjects)) {//Horizontal Collision
while(!place_meeting(x+sign(hspeed), y, osolidobjects))
x += sign(hspeed);
hspeed = 0;
}
if (place_meeting(x, y+vspeed, osolidobjects)) {// Vertical Collision
while(!place_meeting(x, y+sign(vspeed), osolidobjects))
y += sign(vspeed);
vspeed = 0;
}

direction automatically becomes 0 when speed becomes 0. There is no way to change this behavior.

To work around it, you could keep a temporary copy of direction in memory which only updates its value to direction if it isn't 0. That way, you'll always have access to the latest value of direction that isn't 0.

If 0 is a valid value for your usage case of it, refer to the temporary copy if and only if speed is 0, otherwise, refer to direction itself.


... or program movement manually so you have full control over it and don't have to rely on workarounds.

thnx for the info so what am loking att is change the direction to the previous one when speed = 0

it worked i put if speed != 0 dir = direction before collision then but direction = dir after thnx bro for the help uwu
knockback = max(knockback-2,0);
if(knockbackon = 1) {
direction = knockbackdir;
speed = 6.5;
if(knockback = 0) {
speed = 0;
direction = dir;
knockbackon = 0;
}
} else {
if rkey hspeed += accel;
if lkey hspeed -= accel;
if dkey vspeed += accel;
if ukey vspeed -= accel;
speed = clamp(speed,-spdmax,spdmax);
if speed != 0 dir = direction;
if (place_meeting(x+hspeed, y, osolidobjects)) {
while(!place_meeting(x+sign(hspeed), y, osolidobjects))
x += sign(hspeed);
hspeed = 0;
}
if (place_meeting(x, y+vspeed, osolidobjects)) {
while(!place_meeting(x, y+sign(vspeed), osolidobjects))
y += sign(vspeed);
vspeed = 0;
}
if(knockback > 0){
dir = direction;
knockbackon = 1;
}
}
