collision shape what is the best way ?

jonSS

Hello, What could be the best way of doing things ? The collision in an area3D, has 3 small dots named "extents" in the editor.

Should i make the collision the same size has the area cube (yellow cube) using the "extends" dots ?

Or should i leave everything by default and edit it later once the area is on the player "kinematic body3D" ?

Once the area3D is on the player tree. The area ( yellow cube ) gets a lot smaller than its collision shape ( blue cube ).

Also i cant seem to reset the extents dots on editor ?

The problem iam having is that iam editing the area(hitbox) in the player script.

    func _attackBox1( hitname, _x, _y, _w, _h, _z, _state, _anim, dir):
    	hitname.translation.x = _x;
    	hitname.translation.y = _y;
    	
    	hitname.scale.x = _w;
    	hitname.scale.y = _h;
    	hitname.scale.z = _z;
    	
    	hit_st = _state;
    	hit_anim = _anim;
    	
    	hitname.hitFacing = dir;

#----------------------//----------------//---------------------------------
    func _physics_process(delta: float) -> void:
    
    	_attackBox1( $hitBox, -0.07, 0.1, 0.86, 1.2, 0.9, "st_fall1", "fall1" , my_direction );

Since the collision is a lot bigger than the area cube this number's will get very small. The depth value for example (Z) stays at 0.003, to get the collision right ?!?

I think the problem is that you have changed the scale of the collision thing’s parent which will then affect the size of the collision shape.

Thanks but it gets like that by default ... On image 1 of the frist post. The hitbox(area3D) its is own thing, has the child node collision shape/sound effect... The blue cube always gets bigger than the yellow cube i guess...

What was bothering me were the extends, but i manadge to find out were to edit them / right mouse click on box shape / edit... The extends can be edited there for me the precise size is 0.2 on all x,y,z... i hope its the same for everyone

[edit] still is confusing the yellow cube is composed by 2 lines. With the blue cube extends by 0.2 it stays 1 inch inside the yellow cube. I dont know if this leaves some margin of error if the hitbox node is scaled by 10 or 100... 1 inch could mean 10 pixels of distance or something ?!?

still is confusing the yellow cube is composed by 2 lines.

The two orange lines are to make the selected object line appear thicker, as the line cannot be made thicker otherwise. It's a purely visual effect. The collision shape's size is represnted by the blue lines (or gray if the shape is disabled).
