Welcome to How to RTS
I’ve been recently interested in RTS Games (Planetary Annihilation and Supreme Commander 2 in particular), so I plan to slowly build up an RTS engine of my own. Along the way I’ll do some posts and miniprojects explaining and showing the various things involved.
I’ll be posting mini examples as runnable javascript apps to explain how things work.

Plan
This is a rough list around what I plan on developing and writing up.
- Tower defense essentials
- Pathfinding - Dijkstra / A*
- Steering and Flocking
- Modern Pathfinding - Flow Fields, Flow Fields with Formations
- How to calculate/render vision
- How to merge range weapon circles for rendering
- AI - Planning
Posts so far
Rendering combined range rings
When you have multiple units, rather than rendering one circle for each of their weapon ranges, it looks nicer to draw the outline of all of the ranges instead
