Draw to Tiled Canvas #27

Open karai17 opened 9 years ago

karai17 commented 9 years ago

Okay so here is the basic idea:

Divide canvas into a grid
Determine which cell(s) an element belongs to at any given time
If any changes occur to an element, declare the cell(s) invalid
Redraw any invalid cells

Anything that could affect the visual status of a cell would make it invalid, such as an animation, an element moving, an element scrolling, etc etc etc.

You should maybe call this "Spatial Dirty-Flagging" or something, I confused this with Tiled/mapeditor at first.

Bobbyjoness commented 9 years ago

Doesn't have a potential to make all cells be marked as invalid any way do to a resize or something similar?

karai17 commented 9 years ago

I haven't quite decided how I will do this yet, but I will have an option to flag the whole DOM for redrawing.
