I'm trying to use the SampleSprite example as a base to implement rendering from a spritesheet.  From what I've gathered so far, it's using the VertexBuffer to define the rectangle of the sprite.  Although I haven't solved it yet, does anyone have a basic solution for this problem yet?

If I figure it out, I'll try to post my solution.

Thanks!

Update: Well, I was able to get something to work using the SampleSprite example.  However, once I clean up the code a little I'll post the solution.  To give you a quick hint of how I solved it, the VertexBuffer was the key into solving the problem.  I had to modify the SetTexture method in the example to be able to calculate the UV coordinates for the spritesheet.

The simple solution takes into account a fixed width/height dimensions for each frame.  I also added properties to keep track of the number of frames by breaking up the spritesheet into rows and columns.  Knowing the width/height and how many rows and columns, I'm able to define a rectangle that will map exactly to the frame I want to render.

I'll post the code and example screenshots once I clean up the code.  Stay tuned.

i had modifed the image sample to display textures from a list. Basically all that I need to implement is the Image.Cropped method to select individual segments of a sprite sheet to add to the list.

Interesting!  I was also looking at the Image Crop example shortly after I implemented my solution.  I would love to see how you did it.  Thanks for sharing!

Let me know if that shows up for you. I put it on private because of the NDA with Sony. Basically all I did was take out alot of the irrelevant code and then move some of the methods out of appMain, It still a work in progress, but it does automatically allocate vertices for each individual tiles.

However, im pretty sure this would be very irrelevant. Im wondering if just making a 2D plane and then pasting textures to it would be more efficient in this case.

Cool!  I'll take a look at this in a few.  Yeah, I was also thinking of trying to create a blank Texture or canvas and create a render method to fill the current frame from the texture data from each sprite.  I'm still trying to get familiar with the Texture2D class.

Thanks for posting your solution and keep up the great work!

Lol, i dont deserve the credit. Thank the dev team. I didnt write the code, just removed the irrelevant stuff and organized the rest of it.
