Support / Re: tk2dCamera.ScreenExtents incorrect when ZoomFactor not 1?

« on: August 21, 2013, 03:44:02 pm »

Thanks, you are right it does work in your package.  After seeing that I did some more digging.  My problem may have something to do with how I am trying to constrain my camera within bounds.

Here is what I'm doing and what I've found:
1. In my Update() loop I process my mouse scrolling and zoom the camera ZoomFactor accordingly
2. After zooming I immediately check my bounds and correct the camera if it is outside of the bounds (when I do this all the calculations seem correct and the camera should be correctly adjusted. I even create a cube with the camera extents at this point to visually see that it is within the bounds - looks correct)
3. Shortly afterwards something calls tk2dCamera.OnPreCull() and that calls UpdateCameraMatrix() which changes the camera extents.  This changes the camera to display areas outside of my bounds. I am not sure what is causing this, any insights into that?

Support / tk2dCamera.ScreenExtents incorrect when ZoomFactor not 1?

« on: August 21, 2013, 05:20:46 am »

I'm not sure if I am missing something here or if there is actually a problem.  I am changing my tk2dCamera.ZoomFactor to zoom in and out of my scene. This works fine.  I am also moving my tk2dCamera position around to pan the scene.  This also works fine.

But when I use tk2dCamera.ScreenExtents to keep the camera within a bounds I am running into a problem.  tk2dCamera.ScreenExtents seem to be correct when my ZoomFactor is 1.  However, when I zoom in or out (ZoomFactor becomes something like 0.625 or 1.25, etc) the tk2dCamera.ScreenExtents no longer seems accurate and my bounds are not restrained correctly.

I've tested this by creating a cube with the same size of the ScreenExtents and positioning it center with the camera. At ZoomFactor 1 the tk2dCamera.ScreenExtents returns 16 width x 12 height and a cube of the same size matches the camera bounds I see in the editor's scene view.  But if my ZoomFactor is 0.625 tk2dCamera.ScreenExtents returns 21.33 width x 16 height and this does NOT match a cube of the same size.  A cube closer to 25.6 x 19.2 looks accurate.

Am I missing something fundamental here or is tk2dCamera.ScreenExtents not returning the actual correct size of the camera bounds?

Ah that makes sense.  I have been reading the v2.2 documentation here (http://www.unikronsoftware.com/2dtoolkit/docs/2.20/html/classtk2d_sprite.html) because I just bought 2DToolkit and assumed it was the most recent one in the docs (I actually have v2.1).

I will checkout the v2.2 beta now, thanks!

Are there any known issues with the beta?

Support / How to set draw/render layer of sprites?

« on: August 18, 2013, 11:26:29 pm »

Hi,

I've recently started using 2DToolkit.  I am converting an older code base of mine that used Sprite Manager 2.  I'm trying to figure out how to render sprites ontop/behind each other with 2DToolkit without manually setting the z position of the sprite transforms.  SM2 had a "drawlayer" property to handle this on its sprites.  I see in your script reference that the tk2dSprite class is supposed to have a RenderLayer property that sounds like it would do the same thing.  However, this property does not actually exist in that class when I look.  How come it is missing?  Is there some other way to handle the order that sprites are rendered in?

Thanks, really liking 2DToolkit so far.
