physics – Change sprite angle on sloping floor

I’ve an issue right here with GameMaker built-in physics surroundings.My participant is designed to be on a skateboard. I need my participant to rotate its sprite, based on the type of fixture(up or down slopes) he’s transferring on.I’ve tried all the pieces i might and all the pieces i might discover, nevertheless it did not assist me a lot, as a result of the article is rotating in a really unusual means.I enabled some flags to see the masks. Additionally, I have been finding out vector algebra and i do know it the angle between vector x pace and vector y pace ought to be the course. Please assist. Here is what i’ve to this point:

1 object which is the participant

Create Occasion:
execute code:

///Initialize the tires
var half = sprite_width / 2;
var halfy = sprite_height / 2;
var tire = instance_create(x-half+12,y+halfy,obj_Wheel);
physics_joint_revolute_create(id,tire,tire.x,tire.y,0,0,0,0,0,0,false);
var tire = instance_create(x+half+12,y+halfy,obj_Wheel);

Step Occasion:
execute code:

//Code

phy_fixed_rotation = true;
phy_rotation = dealing with;

//Transfer him
if(keyboard_check(vk_space)) {
physics_apply_impulse(x,y,0,-100);
}
if mouse_check_button(mb_left)
{
phy_position_x = mouse_x;
phy_position_y = mouse_y;
}
