Hi

I'm trying to move a 3D hero with the mouse.
I use the character features for collision, it works great.

I have made this example, and it seems to work.

I would like to know if it can be improved

Thanks

Hi,
I prefer vector mathematics in this case.
I have rebuilt your example and use my vector math lib that I presented here years ago.
I also took the opportunity to update the lib.
Of course you can also use other libs that are floating around in the forum.

from Scraggle (2D)

I know there was another good Vector Math Library here in the forum, but unfortunately I didn't find it quickly.

The advantage of changing the code is that a direct path is taken to the destination. And not only horizontally vertically and diagonally.

I have been given this code which works. Which i think is what MadBit posted.

function GetObjectContactPoint(obj as integer, pos ref as tPoint)
	f 		as tPoint
	t 		as tPoint
	w		as tPoint
	dot 	as float
	r		as integer
	id		as integer
	
	f.x = Get3DVectorXFromScreen( GetPointerX(), GetPointerY() )
	f.y = Get3DVectorYFromScreen( GetPointerX(), GetPointerY() )
	f.z = Get3DVectorZFromScreen( GetPointerX(), GetPointerY() )

// get a vector that points in the direction the camera is looking
	t.x = Get3DVectorXFromScreen( GetVirtualWidth()/2.0, GetVirtualHeight()/2.0 )
	t.y = Get3DVectorYFromScreen( GetVirtualWidth()/2.0, GetVirtualHeight()/2.0 )
	t.z = Get3DVectorZFromScreen( GetVirtualWidth()/2.0, GetVirtualHeight()/2.0 )

// normalise Vector in the direction of Vector2
	dot = f.x*t.x + f.y*t.y + f.z*t.z
	
	if ( dot > 0 )
		f.x = f.x / dot
		f.y = f.y / dot
		f.z = f.z / dot

HI

Thank you for your answers

I will try your code.

Blinkok : what is "pos", in your function ? The position of the object ?

MadBit : thanks, I will try it

I have made a little change, to get a direct path to the target too, and rotate the character in the direction of the target

Sorry blendo. I should have posed the type which is just x/y/z floats.

Quote: "what is "pos", in your function ? The position of the object ?"

pos is the point on the object where the raycast hits, it is passed as a ref so you can use the values outside the function (To position an object or camera for example)

You still need to normalize the vector when you cast your ray
