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; (notes)
SE_Long_Float delay; (notes)

Notes

Composed of Notes


Reference_Vector

 This specifies the path of the moving light, and shall be of
 vector_type = SE_REF_VEC_TYP_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, specified in seconds, is better characterized as a
 pre-start; it allows a series of lights to appear asynchronous.
