Hi

i would like to know why the capsule for the character is higher than the box (player) ? And how I can fixe that ?

Thanks

(clic on the screen to see the matter)

Look at this post I explained it here.

https://forum.thegamecreators.com/thread/217420

Change these 2 lines.

+ Code Snippet

    characterOffsetVec = CreateVector3( 0.0, 0.0, 0.0 )
    objectOrientationVec = CreateVector3(  0.0, 0.0, 0.0)

You will no longer be able to see the capsule because it will be in side the box.
If you disable z depth you should be able to see it.

The coffee is lovely dark and deep,and I have code to write before I sleep.

HI Stab

I would like to knwo if there is a technic to decrease the y position of my object with a character physic ?

Because it seems the capsule pivot is centered and all my 3D models (player, ennemies...) have their pivot at their feets.

We can see the matter here :

My player should be on the little mountain, and he's flying over

.

Do you knwo How I can fixe that ?

Edit :
it seems the obj3offsetvec can fixe that with :
characterOffsetVec = CreateVector3( 0.0, 30.0, 0.0 )

in :

+ Code Snippet

Function Create_character_controller(player)
	
    characterOffsetVec = CreateVector3( 0.0, 30.0, 0.0 )
    objectOrientationVec = CreateVector3(  0.0, 0.0, 0.0)
    Create3DPhysicsCharacterController(player, 1, characterOffsetVec, objectOrientationVec,0.75 )
    DeleteVector3(characterOffsetVec)
    DeleteVector3(objectOrientationVec)
     
endfunction

But How Can I get that y=30 ?
It's the height of my model (with its scale) ?

If I use :

+ Code Snippet

	
h = GetObjectMeshSizeMaxY(player,1) - GetObjectMeshSizeMinY(player,1)
// message("taille : "+str(h)+"/"+str(GetObjectMeshSizeMaxY(player,1))+"/"+str(GetObjectMeshSizeMinY(player,1)))
    
characterOffsetVec = CreateVector3( 0.0, (h-2)*5, 0.0 )

But I don't understand the h (height of the model) * scale should be 30 and it's 40, or I need to use height/2 for this vector ?

EDIT 2 :

If I use
h = (GetObjectMeshSizeMaxY(player,1) + GetObjectMeshSizeMinY(player,1)) * scale, I can find 30

But I'm not sur that's the technic to get the height (y) for vector3 because it doesn't work with other 3D models.
