Hi everyone! Here is a list of options that are very much needed inside recroom for all of us creators that need effects.
If we would enhance the features of the particle emitter by allowing us to use our own created objects along with the settings below i feel like we will have no issues creating every effect needed for our games / rooms.
I know this list isnt fullproof but its a very good start! I hope you enjoy.
Particle spray properties
Rate
The number of particles created per second. If Type is One-shot, this is the total number of particles fired.
Spray cone
The number of degrees through which particles are fired.  Use 360 to fire particles in all directions.
Type
The Particles object can work in two modes:
Continuous spray will create a constant spray of particles (the default).
One-shot will create a single blast of particles This is useful for one-off effects like explosions or impacts.
Speed
The initial speed each particle is fired at, in pixels per second.
Size
The initial size of each particle, in pixels. Particles are always shown as squares.
Opacity
The initial opacity of each particle, from 0 (transparent) to 100 (opaque).
Grow rate
The initial grow rate (change in size over time) for each particle, in pixels per second. 0 means the particle will always stay the same size. A positive value will make particles grow, and a negative value will make particles shrink.
X randomiser
Y randomiser
The initial offset to the particle's position. You can make particles created along a line or in a box with these properties.
Speed randomiser
A random adjustment to each particle's initial speed on creation.
Size randomiser
A random adjustment to each particle's size on creation.
Grow rate randomiser
A random adjustment to each particle's grow rate on creation.
Acceleration
Change in particle speed over time, in pixels per second per second.
Gravity
The acceleration downwards caused by gravity.
Angle randomiser
Maximum random change to each particle's angle during its lifetime.
Speed randomiser
Maximum random change to each particle's speed during its lifetime.
Opacity randomiser
Maximum random change to each particle's opacity during its lifetime.
Destroy mode
How each particle is destroyed.
Timeout
The time in seconds particles last.
Ty for reading and hope to see this in the future.
