Subject: [PATCH] Expand World.spawnParticle API and add Builder
|
|
|
|
Adds ability to control who receives it and who is the source/sender (vanish API)
|
|
the standard API is to send the packet to everyone in the world, which is ineffecient.
|
|
Adds an option to control the force mode of the particle.
|
|
|
|
This adds a new Builder API which is much friendlier to use.
