How to turn in a sd terrain.

[pfaber11]

I created my terrain and added my camera to it . Now if I try to lean left then camera turns to the right but the camera keeps going in the original direction . I'm gonna put some code up and maybe you'll spot something wrong . I'm currently using PB 6.00 and DirectX9 . Thanks for reading.

Code: Select all

  ExamineKeyboard()
    If KeyboardPushed(#PB_Key_W)
     
      MoveCamera(0,0,0,2,#PB_Relative)
      
    EndIf
    ExamineKeyboard()
    If KeyboardPushed(#PB_Key_A) 
      zt=zt+2
      RotateCamera(0,0,zt,0,#PB_Absolute) 
      ;MoveCamera(0,0,0,2,#PB_Relative)
    ;  MoveCamera(0, CameraX(0), TerrainHeight(0, CameraX(0), CameraZ(0))+10 , CameraZ(0), #PB_Absolute)  
      EndIf
      jump61:
    ExamineKeyboard()
    If KeyboardPushed(#PB_Key_D) 
      zt=zt-2
      RotateCamera(0,0,zt,0,#PB_Absolute)
    ; MoveCamera(0, CameraX(0), TerrainHeight(0, CameraX(0), CameraZ(0))+10 , CameraZ(0), #PB_Absolute)   
     ; MoveCamera(0,0,0,-2,#PB_Relative)
    EndIf 
 MoveCamera(0, CameraX(0), TerrainHeight(0, CameraX(0), CameraZ(0))+10 , CameraZ(0)+2, #PB_Absolute)  
  RenderWorld()

Thanks for reading.

Uff!... no offense, but your code is a total mess
You should learn some programming, I recommend that you see examples of other programmers (here in the forum there are quite a few).
And do yourself a favor and don't use "GoTo" or things get even more complicated.

Your example is still not functional because it lacks images, mesh...
but anyway, I think that what you are looking for to solve your problem is to add "#PB_Absolute|#PB_Local" to the movement of the camera.

[pfaber11]

Well I solved the problem by moving the code for the key input to the end of the main loop and all is good. Played with the code a fair bit too. The reason my code was such a mess is I was experimenting and trying out different stuff and it did get messy . I use goto but sparingly and would be pissed if it was not available . Goto is your friend and must be respected. It is very useful.

[pfaber11]

Well my entity is still going in the wrong direction instead of where it is pointing . I have no idea why this should happen although I can think of a few case scenarios where it could be useful. Could some nice person please explain where I'm going wrong . Thankyou.

[Caronte3D]

Hi, I already answered your question on my last post: ("#PB_Absolute|#PB_Local").
I encourage you to publish a minimal and really functional example so that someone can help you without having to do a lot of work.

[pfaber11]

I'm sorry but I just don't get it . I'll work it out eventually but if you have the answer I would appreciate it thankyou.

[Krix]

What Caronte3D says is that use MoveEntity with mode "absolute" and value "local" like this:

MoveEntity(1,0,0,z,#PB_Absolute|#PB_Local).

Check the help file it's all there at MoveEntity.

[pfaber11]

Hi Caronte3D and Krix. Now I get it . I was on this for a few days although I took a break and with some help got camera follow nailed . Anyway thanks for your time and help. I was so annoyed to be stuck on something I'd done many times in a different system.

[pfaber11]

I'm using this time to make a program to use as my own reference in the future. Not detailed but the basics to jog my memory and I am just about done . just checked and it's 168 lines of code . I did look but could not find a cheat sheet on the web .
Have a nice day.

[pfaber11]

I thought I should show you the code that you guys helped me with for reference in the future.

Code: Select all

  ExamineKeyboard()
    If KeyboardPushed(#PB_Key_W)
      MoveEntity(1,0,0,-2,#PB_Absolute|#PB_Local)
      EndIf
    ExamineKeyboard()
    If KeyboardPushed(#PB_Key_S)
      MoveEntity(1,0,0,2,#PB_Absolute|#PB_Local) 
    EndIf   

So glad I now know how to do this .

[Caronte3D]

Nice!
BTW: In the future, if you post a minimal working example showing the probleme, more users can help you an faster you get a solution
