Learning Resources

I make The Learning Quests: gamified, single-file HTML learning paths for game development. Each one is a set of worlds full of quests and boss projects, with XP to earn as you go, and it runs right in your browser.

Try the Ideas

Three small, hands-on demos of ideas the quests teach. Each one is a simplified example.

Vectors and the Dot Product

Simplified example

Drag the tips of A and B, or focus one and use the arrow keys.

Easing and Lerp

Simplified example

Drag the pink dot along the track, drag the marker on the curve, scrub t or press Play. Easing reshapes t before the lerp moves the dot from A to B.

Formula

A Blueprint Branch

Simplified example

Every tick, this graph checks whether health is low and runs one of two paths. Change the health and the threshold to watch the values flow through.

Game Feel

Simplified example

Collect all six shards. Then switch the techniques off and play again: the same controls, a very different feel. Clear the course once and a ghost of your best run races you on the next try.
