Pick is working realy wired

[Andy90]

Hello  the camera pick is working realy wired for me. You can see it within the video 2023-09-30 02-36-14 (streamable.com). This is my code

 

function Script:Shot()
	--Create a sphere to indicate where the pick hits
	local pickradius = 0.1;

	picksphere = Model:Sphere()
	picksphere:SetColor(1.0, 0.0, 0.0)
	picksphere:SetPickMode(0)
	picksphere:SetScale(pickradius * 2.0)
	picksphere:Hide()

	picksphere:Hide()
	local pickinfo = PickInfo()
	local p = window:GetMousePosition()
	if (self.cam:Pick(p.x, p.y, pickinfo, pickradius, true, Collision.Prop)) then
		picksphere:Show();
		picksphere:SetPosition(pickinfo.position);
		local name = pickinfo.entity:GetKeyValue("name");
		pickinfo.entity:Hide();
		System:Print(name);
	end
end

I got another problem with pick. It seems pick is ignoring animations. 

Without animation 

with the idle animation

Based on your video, I think the problem is that you are expecting it to pick the closest object. There is an optional value you should set to get this behavior. Otherwise, it just acts as a line-of-sight test and returns if any object is hit.

Picking does not work on animated models because the vertices only move around on the GPU. In my AI scripts I handled this by using the box pick mode on all children of the model, then disabling picking on the model itself:

	self.entity:SetPickMode(Entity.BoxPick,true)
	self.entity:SetPickMode(0,false)

This provides a close but efficient way to intersect an animated model with bullets and things.

Thank you, this is very helpful. I believe I've properly configured the parameters in my pick function to acquire the closest target. However, there's a chance I may have misunderstood something.

self.cam:Pick(p.x, p.y, pickinfo, pickradius, true, Collision.Prop)

I also edited the model a bit because at some parts of the body was no hit registration. So i added some spheres and asign them an invisible hitbox material. Works great so far

This looks correct to me.

I think it has something to do with the model. After I fixed the issue on the zombie model today, the hit registration on it is now perfect. It might be due to the surface size.

Did you self-scale the model ? or scale via the editor's 'Resize' feature, it actually makes a huge difference.   I found it way helpful to scale any animated mesh or boned objects outside of leadwerks and just bring it in at it's actual size, You cant resize then collapse a boned mesh in the editor without deleting it's hierarchy and that screws everything up..  Normal meshes you can resize in the editor then collapse when your done and it will retain a 1 to 1 scale which is what you want for picks and such.

Im not sure anymore tbh. But i think it was the editor.
