I'm prototyping a 2d HTML5 game with similar interaction to Diablo II. (See an older post of mine describing the interaction here: How can I imitate interaction and movement in Diablo II?How can I imitate interaction and movement in Diablo II?)

I just got the player click-to-move system working using the Bresenham algorithm but I can't figure out how to efficiently render the player's avatar as he moves across the screen. By the time redraw() is called, the player has already finished moving to the target point. If I try to call redraw() more frequently (based on my game timer), there's incredible system lag and I don't even see the avatar image glide across the screen.

I have a game timer based off this awesome timer class: http://www.dailycoding.com/Posts/object_oriented_programming_with_javascript__timer_class.aspx

In the future, there will be multiple enemies chasing the player. Fast pace is essential to the experience.

What should I do?
