One of the areas I easily get the most requests for tutorials on is math.  Therefore I've created a new series of tutorials on exactly this topic, covering some of the most commonly encountered game dev math challenges.   Right now there are 6 tutorials, with more in the works.  They include:

Table of Contents

• Velocity and Angular Velocity ( two in one )
• Rotating one element relative to another
• Rotating to face another object
• Axis Aligned Bounding Box Part One -- Intersections
• Axis aligned Bounding Box Part Two -- Rotation

Each tutorial comes with a complete demonstration application ( in browser ) with complete source, a smaller section with just the math related source code and a description, often with pictures.

This is going to be an ongoing series, so I will update here as I add more.  If there are any specific topics you would like me to cover, please post them here and I will try my best.

Hope some of you find this useful.

Yay, maths.

How about rotated rect x rotated rect collision?

Thanks for the tuts, I enjoyed reading them.
It never hurts to brush up on some maths.

Yay, maths.

How about rotated rect x rotated rect collision?

I finished off on the two aabb collision posts, getting collisioned out for a bit

Intend to cover collision circles, as they are easy and solve the whole rotation issue being circles and all.  Will also try convex hulls ( which essentially a rectange is I suppose ) at some point if I can shrink it down to fit a recipe.

[Serapth]

Updated, collision detection using circles.

By request I created another recipe, Handling sprite based shooting.

It will create a bullet traveling in the direction you clicked.  The distance away determines the speed of the projectile.

This is a nice inniciative. Gonna bookmark this for whenever I need some help with math. Thanks.

I think you should maybe add the latest tutorials to the list in the original post, though, if possible. For now you're only on one page, so no big deal, but if you keep going you'll end up with the tutorials lost in between posts and pages, and may become hard to find.

Thanks for sharing this, always nice to have some maths tuts related to gaming

That's true, but I'm really really really lazy.

I should actually just remove all links and link directly to the table of contents post.  When I started the series, it didn't exist, so I announced them as I created them.


By the way, to the community, any requests?  I've been somewhat idle on creating more, but am always open to requests... if I can.

This may not suit your recipe style tutorials, but an introduction to vector math may be useful to your readers.

So far I have seen a lot of great explanations of how to achieve results with trigonometry. Many of these same results could be explained with vector math.

You could even reuse some of your old topics in the introduction to Vector maths. This may help your readers appreciate the relationship between trigonometry and vector math.

I could see the following tutorials benefiting from an explanation using Vectors:

- Velocity and angular velocity
- Rotation around a point

Thanks! This is great.
