You ask for ready-to-use-code.
That is not helpful. It is just asking others to doing your work.
You could ask, what you doesn't understand in this example
to change it, to solve your problem.
I have written the logic behind it.
That should help you.
If it doesn't help you, i can only say:
"Use the examples given with PureBasic. If there aren't enough,
you can search other places for more examples."
If you are a beginner, you need to learn very much. Thats not
the problem. All programmers have done this and all are still
learning. If 3D is to much for you yet, you could begin with 2D.
PB is not the right choice to program 3D-Games as a beginner.
Not yet, if you need information about 3D-Engines, you should
read some books over this or look on the net for generically
informations about 3D-Programming.
It is important to learn, how to learn more. If you haven't
read the hole help-file from PB, than you should do that now.
You will find many information about some functions, you
doesn't know yet. If you have problems by programming
something, you can ask what you make wrong. But like you
doesn't need to ask your questions here, we must not answer.
Thats also why only one people have answered.
And yes, there is no forum where you will get such answers
But some times, also like here you see, there are still some
people who have to much free-time
, like me i think.
