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

 This is the speed, specified in metres per second, at which the
 light moves along the path.

delay

 This value, specified in seconds, is better characterized as a
 pre-start; it allows a series of lights to appear asynchronous.
