Parent camera issue?

[Andy Gilbert]

If i parent an object to the camera entity the object dissapears, im not sure where too, i assume it becomes invisible. Why is this?

 

Thanks

The object perhaps move to camera position ?

I don't know what means parent ?

 

Have you some code to show ?

How did you created the camera ? by code or in the editor ?

[Andy Gilbert]

Hi Yougroove, to parent an object you are telling it to inherit properties of another object:

What im saying is that when i parent an object to the camera it dissapears.

can you move the object forward?

[Andy Gilbert]

Ok so this is the code, this script i attatch to an object and drag the camera entity into the target.

 

Script.target = nil--Entity "camera"

local tposition = Vec3()

function Script:Start()
tposition = self.target:GetPosition()
tposition = Vec3(tposition.x,tposition.y,tposition.z)
self.entity:SetParent(self.target)
end

 

The object dissapears, ive tried offseting it from the camera but no show. If i set the target to another object in the editor it works fine.

Did you frag camera on target slot ?

Could you verify in debugger if target is not null ?

 

Or make the test :

 

if self.target not null do stuff else return

For a camera system do as i made, without Parent, and use direclty model and camera positions.

Yes i dragged it in and yes an earlier version did check for null, but still no luck.

 

Doing your way wouldnt work for what im doing, the correct way would be to parent against the camera entity, like in le2.

 

And im sure it should work, but not doing.

Can you post your project? I can't tell what the position of the entity and camera are so there's no way to know what's going on.

[Andy Gilbert]

Yes i should be able to, but the camera is one created in the editor, along with the object im trying to parent to it.

 

I then assign the above script to the object and drag the camera object into the target.

So I tested out your script by attaching it to a box in Darkness Awaits, I then put the camera in the entity field.

 

When I ran the game the box seemed to move how you would expect it to when parented to the camera.

 

 

If I had to take a random guess I'd say that the object that you are setting as a child of the camera is being moved off screen or behind the camera.

 

I'd check their positions real quick (throw this in after the call to set parent and then check the Output box after running the game:

 

System:Print("camera / tposition: " .. tposition:ToString().."  object position: "..self.entity:GetPosition():ToString())

So the function don't work correctly and we should avoid use it ?

As far as I know the function is working properly. If it's not let me know!

[Andy Gilbert]

It is, was my code in the end!

So what is the code solution with that function to work well ?

 

I'm confused ?
