rendertoimage won't work in my code? help.

[stevmjon]

hello

    if i open a new project and use rendertoimage, it works perfectly.  i am using V1.63n / IDE 1.15f .  BUT, in my own code i cannot get it to work properly. is there an instance or condition it won't work? if so, i must be doing it without knowing.
 
what happens is i can cls rgb(), and this works, but any graphics like dot/line etc are all drawn to the main screen and not to the image. i make sure that the image index no. is greater than zero. why would the colour be in the image, but nothing else?

here is a brief approximate outlay of where it is in my code:

do
rendertoscene
clear scene
some code
capture depth 3
gosub new_image_here:
draw all sprites
draw camera 1
loop

new_image_here:
rendertoimage 9
cls rgb()  *works perfectly
line   *doesnt work* this draws to the main screen
dots  *doesnt work* this draws to the main screen
render to scene
return

any advice or pointers would be appreciated.

  thanks  stevmjon

 If capture mode is enabled, they you'll have to disable it before rendering to a different surface.

PlayBASIC Code: [Select]

 ; create a new camera. Which will be attached to the current surface (the screen) 
   MyCamera=Newcamera()


 ; create a new image
   MyImage=Newimage(200,200)

 ; start of main loop  
   Do
      ; Capture all draw events to the scene cache
         CapturetoScene
  
      ; Clear the Scene cache 
         ClsScene

      ; call a routine to draw to an different surface
         gosub DRawingStuffToImage

      ; draw (capture) this image to the scene Capture
         drawimage  MyImage,mousex(),mousey(),false

      ; Draw all the items in the scene through this camera
        drawcamera MyCamera

       Sync
   loop



DrawingStuffToImage:
   ; Enable immediate rendering, rather than caching 
   DrawGFXimmediate
   ; direct all draw to this image
   RendertoImage  MyImage

       ; draw stuff directly to my image
          Circlec rnd(100),rnd(100),rnd(10),true,rndrgb()

    ; Restore Capture mode before returning to the main loop
    CaptureToScene
 return

thank you very much kevin.

it now makes sense to me. i spent a whole day wracking my head around this.

much appreciated,  stevmjon
