Problems with the collision!

Game Engine Game Engine Support and Discussion

Hi Guys,
I’m comparably new to blender. Having just managed to create some surface to be flown over by a camera in all three axis, I’m having problems with the collision of the camera with the surface which always reacts too early, to say when the camera is still some distance away. I’ve already set the size values of both the surface and the camera to a minimum.
Furthermore, only fragments of this surface are shown in the game engine in textured and shadered mode although it is correctly rendered and shown in solid mode…

Could you be so friendly to have a look at it? You can move the camera with the arrow-keys and the WASD-Buttons.

Any help would be appreciated!

You might try scaling the camera, or just parent it to an object slightly behind, that should also help with the clipping problem.

Thanks for your time, fireside!
I’ve made the camera a ‘ghost’ and parented it to a dynamic icosphrere. But now, they are both floating through this plain. Do I have to control the sphere? If yes, is there any possibility to transfer the logic bricks to it? And do you also experience these problems when starting the ‘game’ out of textured-mode?

Yes, you have to control the sphere. To transfer the logic bricks select it first, then select the camera, then go to the object menu and copy attributes/logic bricks. You’ll then need to delete the bricks from the camera. You can make the sphere invisible if you want by clicking on invisible when it’s in uv face select.

Yes that works fine, the only problem is that the camera can accidentally pass through a hill if you move the sphere sidewards.
But my biggest problem at the moment is the vanishing surface in the game mode. If I enter this game mode out of textured or solid mode the ground is only displayed in fragments. If I start the game out of the shaded mode, it runs normally. Do you have any idea how that can be changed?

It could be your normals. Try selecting the groundplane, go into edit mode, hit “a” to select all vertices of the object, then hit control “n” and answer yes.

Yes, it seems to have something to do with the normal maps. When i recalculate them, the texture sort of flips to the backside. If I start the game looking at this side, the same problems occur. The front however is displayed in white fragments in object mode and without any texture in game mode.

would there be a way to deactivate the normals for a test?

All right, instead of searching all the settings, I’ve simply modelled some other surface and it’s working fine without these fragments. I must have activated too many buttons I don’t know in the course of developement^^
However, Thanks to you!
