Hi there

I am trying to get my head around Dark Basic Pro and the programming behind it. Using Cshop i have created a small level, and want to put a skybox around it. I am not having much luck with scale object of the skybox

it looks like the x,y and z are too much, but when i run it, its not working at all, i would like the skybox to wrap around my level, thats it.

Also with Camera, how do i set the camera on where to look, at the moment, it pointing out, but i want to turn it to 180 degree, so it pointing towards the level

Please could someone have a look at the code, and see when i am going wrong with this



Please help

Kind Regards

First thing is to check your camera range with Set Camera Range, the sky sphere is most likely drawing beyond this. The default camera range is, min=1, max=3000 if I remember.

Secondly, using either Set Object or Set Object Cull you will need to tell your object to draw all faces, this way you can see the sky from the inside the sphere. Set Object 2,1,1,1,0,0,0,0 should do it. (working off the top of my head here)

And Point Camera is your friend

I could be wrong, but this is my understanding...

Set Object Cull is used to ensure the skybox doesn't hide your landscape. Your skybox can be smaller than the scene, but the objects behind it show through.

Multiplying the size of the skybox by -1 turns it inside out and thus puts the texture on the inside, and also solves the collision issue of being inside a box. That's how I do it anyway.

Hi there

Many thanks for the reply. I got a bit working now, thank you both, but the sky box is still not showing how i would imagine it be

I have uploaded the project files with the media files onto my website, kindly please could someone have a look into it, and see where i am going wrong, and if possible, advise or put right the code. I would be grateful for your help

Here is the project file

works here, not too sure about the fog colour or density though, I inverted the skybox (it was the wrong way up) and made it insensitive to ambient so that you can`t see the seperate faces apart from where the texture joins, also the skybox was set to be wireframe, so I turned that off and fiddled with the camera range, cheers.
