Pocket Defender

Testing how the locking feels like. The timing seems plausible - it depends on the accuracy of aiming: The better the aim, the quicker the lock on happens. I think this could enable special enemies that are very good at evading rockets...

I'm working on a smart missile upgrade where the missile can lock on targets. However, the lock on must happen by aiming with the missile steadily at the target. I'm not sure if this'll work out. 

  Added a new feature to the particle system  that I am working on for Actionscript  using Stage3d: additive color factors. The animated gif shows how the additive color effect allows giving the particles a white color at the end of their lifetime. The color can be chosen freely of course. For clarification: Only one single texture sprite is used for drawing the particles (RGB+Alpha). A majority of items on my feature list is implemented by now

Linear velocity and gravity, influenced by motion drag

Multiplicative color influence

Additive color influence

Size influence

Rotation speed and drag factor influence

The system still qualifies the requirements I had for the rewrite regarding the performance, important for mobile systems:

Lightweight particles (76 bytes - 19 floats)

Simulation entirely done on the GPU

Two drawcalls at most

Remaining features are:

wind influence

emitter system

cpu based particle death detection

Spawning particles on top or bottom of the existing particles

Limitation (that I am not happy with):

Currently 15 vectors are used as particle type parameters; This limits the particle simulation to about 8 distinct particle types in one system. Could be countered with more heavyweight particles that carry more information on their own - which would enable more versatile usages.
