Lowerdash Fire Demo

This is a demo built using Lowerdash. This uses the same modules as the ball demo but with a particle emitter subclass. The download is also compiled/concatenated!

Instructions:

You can check out MAIN in the editor to see the code that compiled the "DIST" file! The particle emitter is a special case where the "NO DELETE" clause on Lowerdash right now might lead to a memory leak. So how do you write an efficient particle emitter?

Object Pools!

An object pool is a module with a private pool of usable objects.

MODULE Emitter
PROTO PhysBody

VAR particles$[maxParticles%]
FOR I=0 TO maxParticles%
  particles$[i]=CALL(new("Particle"))
NEXT

Now every instance of Emitter has access to maxParticles% number of particles. The emitter could use all the particles, calling a draw method like a stamp. Or the emitter could SHIFT or POP particles from this array while its using them, and UNSHIFT or PUSH them back when its done.

Notes:

LOWERDASH 0.4 BETA IS OUT! This program still uses 0.2
