public static void DrawDottedLines (Vector3[] lineSegments, float screenSpaceSize);

Parámetros

lineSegments A list of pairs of points that represent the start and end of line segments.
screenSpaceSize The size in pixels for the lengths of the line segments and the gaps between them.

Descripción

Draw a list of dotted line segments.

"Draw multiple dotted lines in sceneview.".

// Draw lines to the connected game objects that a script has.
// if the target object doesn't have any game objects attached
// then it draws a line from the object to 0,0,0.
