comment What's the fastest way checking if two moving AABBs intersect?
Thanks for the update (and hurra for the schemes :-)), this was not my question but helped me understand that your algorithm already handles the case when A completely passes through B.

comment What's the fastest way checking if two moving AABBs intersect?
Thanks, most interesting. Could you please explain how do you handle the case when A and B intersect during the move, but end the move without intersection ?

comment Rotate arrow on canvas
You're welcome. For the circle border, it's the common mistake : you forgot to beginPath() before drawing (stroke()) the line. (jsfiddle.net/gamealchemist/jxrdtLxx/4). Yo !

comment Movement on objects in 2D tile/grid based game
While i quite agree with you, @StephaneHockenhull, i'd like to say again this point, that only people that understands this answer in a snap will benefit from it : while i belong to those peoples, i'd think useful, in a 'wiki' way, to go into further details. (Maybe that comment would apply to my post... ??? :-) ). Regards.

comment Movement on objects in 2D tile/grid based game
If i may comment, i think you (stephane / classic) have just a misunderstanding. I think your answer to 'Can we consider that a hint into some direction is an answer ?' is different. I'd say this answer is right, but would benefit from some elaboration -maybe only the ones that already had this solution in mind will completely understand it-. To Erez : tell us more !

'I tought it had something to do with' ... Use a profiler (In Chrome you have one), so you'll know for sure who's the culprit.

comment Balancing fight script in Text Based Javascript Game
This is the kind of issue i would solve by re-designing the code : Have clear objects with defined responsabilities, and de-correlate the codes handling 1) the input / 2) the game / 3) and especially the output.!! Clarify !! I started a bit here : jsfiddle.net/vxbp7fxL/6

comment How do I procedurally create a directional light cone with an HTML canvas?
Then you might use the 'ligther' globalCompositeOperation an either a solid fill or a gradient, playing on globalAlpha. You'll have to tweak the color/gradient/alpha to make it nice. Obviously, real shadow need more work (to stop on walls), but you can already improve that with some clipping. Small example with colors/gradient/clipping here : jsfiddle.net/gamealchemist/pgb3bhxj

Are you using webGL or the context2d ?
