LineRenderer.SetPositions

Parámetros

Descripción

Define las posiciones de todos los vértices en la linea.

This method is preferred to SetPosition when setting all positions, as it is more efficient to set all positions using a single command than to set each position individually.

See Also: numPositions property.
