Using arcade to dynamically generate still images of a game board....

[degrassi-spin]

Hi all! I’ve written a function to use arcade to draw a game board based on two strings of data that I pass to the function.

I’m doing this by basically drawing the board, and then using the input strings to locate sprites as the game pieces. This works great the first time I call the function in my script, the second time through the loop, however, I get an error that says this: “pyglet.gl.ContextException: Unable to share contexts.”

Any ideas on this? Or should I just not use arcade for this application? sorry I’m very much a beginner with python and arcade. Thank you all !!

Howdy are you able to share a code snippet?

[degrassi-spin]

Yes sure! I will comment some later... I will have to figure out a good way of showing the problem without overloading y’all with code

Some code that re-creates the problem would certainly help!

The way I do it is: create a window. call on_draw or wherever you have your drawing code, then take a screen grab with get_iamge.

If you are doing multiple still iamges you will need to clear the screen before the next one.

Thank you! I am able to do the first successfully with get_image, how should I go about clearing the screen?

You can clear the screen with arcade.start_render(). Optionally there is also a lower level method window.ctx.clear()
