raycast to show hidden objects

[DooMAGE]

Hello,

I'm trying to modify the FPSPlayer.lua to show hidden objects with the flashlight, but its not working.

What I am doing wrong?

function Script:UpdateWorld()
  local pickinfo=PickInfo()
	
  local p = self.flashlight:GetPosition() 
    if (self.camera:Pick(p.x,p.y,pickinfo,0.5,true)) then
      pickinfo.entity:Show()
    end
end

Edit - I guess I should use world:pick instead?

I didn't think pick worked on hidden objects.  Are you sure it's supposed to?

I think it works https://www.leadwerks.com/community/topic/2351-parented-hidden-objects-are-visible-for-raycasts/#comment-21510

Also I am trying to debug with:

System:Print(pickinfo.entity.position)

And it only shows "0.000000, 0.000000, 0.000000" no matter to where I look.
So I think I am using pick wrong :/

In your case I'd check it with a visible entity and see if the pick returns true or false.  If it returns true, just make the entity invisible and you'll know if it can pick it or not.

Yeah, looks like pick wont work with hidden objects (makes sense), and also earlier I was testing with a CSG object, and now I remember that CSG with no scripts is not an entity.

/edit You can hide objects with pick

Update.

It's working now, I use world:pick to raycast and test if the pickinfo I got is the object I want to show.
Since the raycast wont work with hidden objects, I am changing its materials.

Now the catch is, How can I detect if my raycast is not hitting the object I got before, so I can put the original material back?

Tried this but my lastValidPickinfo thing is not working:

if self.entity.world:Pick(p0,p1, pickinfo, 0, true) then 
  if pickinfo ~= nil then
    if pickinfo.entity ~= nil and pickinfo.entity:GetKeyValue("name") ~= "" then
      self.lastValidPickinfo = pickinfo
      pickinfo.entity.script.showObject = true

      if self.lastValidPickinfo.entity:GetKeyValue("name") == "" then
        self.lastValidPickinfo.entity.script.showObject = false
      end
  end
end

Some pseudo code:

if pickinfo ~= nil then
	if pickinfo.entity ~= nil and pickinfo.entity:GetKeyValue("name") ~= "" then

		--If there is a lastPickInfo, compare it to the current pickinfo name
		if(self.lastValidPickinfo ~= nil then
			if self.lastValidPickinfo.entity:GetKeyValue("name") ~= pickinfo.entity:GetKeyValue("name")) then
				--Now the pick is different than previous picked obj
				 self.lastValidPickinfo.script.showObject = false
			end
		end
		
		self.lastValidPickinfo = pickinfo
		pickinfo.entity.script.showObject = true
	end
end
