Have to prevent particle spawn where

• Particle is invisible, prolly alpha < 0.1f
• Particle color matches background

Then we need a little more functionality

• And add ability to add custom colors which
• Will be the only where particle is allowed to spawn
• Will be where particles wont spawn

With this we have a very powerful tool!

We can create custom maps programmatically

• To define color changes acc to the map
• Make particles spawn only at specific locations
• Create awesome effects using heat maps

To get more power with this tool, we'll can

• Create another similar effect which effects the speed instead
• Interestingly we can add size too

• Specify where to bake

or

• Save instructions
• Duration of the bake --> FPS
• Play the result

Life system doesn't work Gdx.graphics.getDeltaTime() is a very bad way
Conversion mistake

The texture need to be redone for integration with json system.

Main tasks:

• Simple texture

• Random textures

• Animated texture

I need something with the least class as possible like two max but one will be greater.
Need changes in ParticleSystem, Particle for that and in ParticleType

Approximation of time : ~3 hours

• x particles per y seconds
• Random particles per y seconds / inner screen

• Find a archive based format that is compatible with java and doesn't require de-compression
• JSON all
• Pack texture, JSON and also the bake result

• Randomize rules
• Randomize colors + lights forces
• Randomize physics variable

• Create constraint manager
• Light constraint
  • Color constraint
    • To r
    • To g
    • To b
    • To a
  • Light distance constraint
• Forces constraints

Ex of constraint : Radius and/or intensity of lights change with noise function --> Value between 0 and 1 returned by noise(x, y) will be a factor for these parameters

Ex of constraint : Particles go nears a certain position and slow down

• Emission in one direction
• Emission in all directions Edit : Radial
• Brownian force
• World gravity and physic factor
  • Mass / friction
  • Dynamic body

All the particle in world physic mode seems to spawn at the same point near (0, 0)

Time is in milli-seconds

• --> seconds

After a moment, Texture particles became black

• Fixed

• Fix it!

• Texture particles (point, halo effect, lights effects)
• Life of particles --->
  - Survive x seconds outer the screen
  - Survive x seconds then fade
• Number of particles emitted --->
  - Always x particles inner the screen
  - x particles per second
• Duration of emission --->
  - Infinite
  - x seconds
