How do I make enemies and/or seperate entites?

I'll begin working on a follow up article shortly which will probably include how to make simple enemies.

I see how you shamelessly put a link in the Links() section to your article D:

Well, it is a link :-) And what good did shame ever do us anyway?

Also, someone asked about license and such for the example code. The examples are free to use under the MIT license, I'll try to get it noted somewhere in the article.

anonymous: Did you read the Permadi tutorial ? Once you undestand the math, adding sprites in the map is straight forward. You just need to compute their distance and relative angle.

Hi Jacob,

I was recently wondering how feasible it would be to create a 3D CAD program in JavaScript using the canvas feature. What are your thoughts on this?

Hi Andrei,

I guess that depends on the complexity of the 3D models you're be working with, ie. how many points/polygons and do you need full colored surfaces or are wireframe models are enough, etc.

It's absolutely possible, though. It's just a question of how well it's going to perform.

Hi Jacob,

Thanks for the reply. It seems that if one puts some constraints on the project (no rendering/texturing except for wireframe/solid objects, optimized for say Chrome's V8, etc.) the project could be rather easily accomplished.
