Constraints

Composed of (two-way)

Component of (two-way) (inherited)

Inherited Field Elements

This class has no inherited field elements.

Field Elements

SE_Long_Float speed; 2
SE_Long_Float delay; 3

Notes

Composed of Notes


Reference_Vector

The <Reference Vector> component specifies the path of the moving light and shall be of vector_type = SE_REFVEC_MOVEMENT_DIRECTION.

Fields Notes

speed

The speed field specifies the speed, in metres per second, at which the light moves along the path.

delay

The delay field specifies in seconds the time to delay before the light behaviour starts. This allows lights to appear asynchronous.
