# Variables

#### Anim Vars <a href="#anim-vars" id="anim-vars"></a>

Generally for anim vars there isn’t much to configure from a properties points of view. They are commonly used via a macro such as the following which is supported by crowd animation.

In terms of limitations it’s worth noting that the current implementation of the Anim Vars encodes all data as float. Internally Boolean properties (e.g. Is Moving above) will be converted on the CPU before being sent to the GPU crowd animation system as a floating point type. If these flags are used for transition logic between states there may be floating point inaccuracies and imprecision in comparisons.
