Hi, I have a problem hooking the camera to an entity that casts a shadow on Fastext, I thought I had solved but the problem continues, showing a transparent blue box near that body that casts a shadow.

Any ideas.

Hello, please use Fastext aid, the problem is when I use a camera hooked entityparent the Jeep, the shadow does not go as it should be.

=( help me please!!!

It's possible its getting confused with parenting and local vs global coordinates.

'm in serious trouble with this, the problem happens when I hook the camera to the Jeep, but if I do not work properly. = (

Thanks for Answer.

Cubo = CreateCube()

EntityColor Cubo,255,0,0
PositionEntity Cubo,0,2,0
ScaleMesh Cubo,.5,.5,.5


PositionEntity Camara,0,1,-5

Sol = CreateLight()
RotateEntity Sol,90,0,0


Fuente = CreateCube()

Everything is fine, but the real problem is when I hook the camera to the hub, everything goes to hell.

I told you the problem so fix it. Don't parent it, dude.

Rob	(Posted 2010) [#7]

Try this way:

1. Parent a pivot called fakecamera to the car the same as you would the normal camera.

2. Then in your main loop:

PositionEntity camera, EntityX(fakecamera,1), EntityY(fakecamera,1), EntityZ(fakecamera,1)

RotateEntity camera, EntityPitch(fakecamera,1), EntityYaw(fakecamera,1), EntityRoll(fakecamera,1)

This will leave the camera free and not a child of any mesh so you will avoid this bug. Thats the best way of dealing with stuff you're not getting quick answers for.

@Yue: I have understood where a problem. Camera shouldn't have the parent who is caster or receiver! Or on another... Casters and receivers shouldn't be camera or have childrens, which are camera!

Use the decision from Rob, but the fakecamera entity shouldn't be real camera (it is very undesirable) - let it will be pivot!
