Draw a line between different objects. The decorated field need to be a GameObject/Component or a Vector3/Vector2, or a list/array of them.

You can use right click to show/hide handles.

Parameters:

• string start = null: where does the line start. null for the current field.
• int startIndex = 0: when start is not null, and the start is a list/array, specify the index of the start.
• string startSpace = "this": the containing space. "this" means using the current target, null means using the world space, otherwise means using a callback or a field value
• string end = null: where does the line end. null for the current field.
• int endIndex = 0: when end is not null, and the end is a list/array, specify the index of the end.
• string endSpace = "this": the containing space. "this" means using the current target, null means using the world space, otherwise means using a callback or a field value
• EColor eColor = EColor.White: color
• float alpha = 1f: the alpha of the color. Not works with color.
• string color = null: the color of the line. If it starts with #, use html hex color, otherwise use as a callback. This overrides the eColor.
• float dotted = -1f: when >=0, draw dotted line instead.

And also DrawLineFrom, DrawLineTo as a shortcut to connect current field with another:

• string target = null: target point of the line from current field
• int targetIndex = 0: if the target is a list/array, specify the index of the target.
• string targetSpace = "this": the containing space. "this" means using the current target, null means using the world space, otherwise means using a callback or a field value
• string space = "this": the containing space. "this" means using the current target, null means using the world space, otherwise means using a callback or a field value
• EColor eColor = EColor.White: color
• float alpha = 1f: the alpha of the color. Not works with color.
• string color = null: the color of the line. If it starts with #, use html hex color, otherwise use as a callback. This overrides the eColor.
• float dotted = -1f: when >=0, draw dotted line instead.
