This is a demo of the new panning feature of the RPG-style battle engine I'm writing for Ren'Py.
The code demo isn't quite like this, I'm just applying the ActivePanner feature to the old isometric grid demo 'cause it gives a better idea of how the enemy turn looks. Apologies for some skipping during movement, it's caused by a Ren'Py bug which cropped up recently. Video captured by CamStudio, which made the whole thing a little choppier than it is live.
The reason for the random pauses while the enemies are moving is that there's a huge 'So-and-so is doing this' banner at the top of the screen which YouTube helpfully cropped out for me automatically.
