 +Controllers are used by game programmers to adjust the particle emitter. In general the artist defines the controller ranges but game programmers can overrule them to make their live easier. This does not interfere with the particle parameters. The output of the controller is the **Value** linearly mapped from the range **Minimum Value -> Maximum Value** to the range **0 -> 1**.
 +
 +Controllers are typically accessed by the game developer using the unique **Controller Name** (case sensitive). This allows to mix and match different animators with differing controller setups (count, ordering and ranges) as long as the required names are present.
 +
 +The controller list is an ordered list. For this reason controllers are shown with their index number too. Game developers can use this index number as an alternative to controller names.
 +
 +The **Clamp value to range** check box determines if the input value is clamped to the controller range or wraps around if going past the range.
 +
 +The **Freeze controller value** is used only for preview purpose to stop a controller from updating its value dynamically.
