Sprite dynamically updating from dataURI

Hey all,

I have a multiplayer game where one player's screen is converted to a dataURI and sent through the game server to the other player. I'm trying to overlay this screen image in the other player's game so that he can see what the first player is doing. This is done continuously, so the sprite should update to reflect it.

I tried using BitmapData but can't seem to get anything working.

Does anyone have suggestions for how to implement this?

What exactly are you trying to achieve? Do you want to 'stream' player1's game to player2? Like 'filming' his game and send the images to player2? This seems very, very unefficient. It's gonna be a huge load on the servers and very resource-consuming for the clients as well. No game ever does this.

 

What you should do instead is both players having the code for the game logic, and just send lightweight messages with users actions in it. So that the game on player2's screen will update regarding player1's actions. This will be wayyy lighter and more seamless for both.

Yes exactly. In this case though it's a very low res "heatmap" of the game state, not a full fidelity image. Creation of this heatmap only takes a few microseconds.

Ultimately what you're suggesting sounds much better, especially to avoid cheating, but I'm just in the prototyping phase now trying to gauge whether the idea is fun.

In the short term, is there a way to achieve this constant redrawing with BitmapData or some other means?
