Draw a sphere in the scene like Unity's SphereHandleCap.

Parameters:

• float radius = 1f: radius of the sphere. If the target field is a number, use the field's value instead
• string radiusCallback = null: use a callback or a field value as the radius
• string space = "this": the containing space of the sphere. "this" means using the current target, null means using the world space, otherwise means using a callback or a field value
• float posXOffset = 0f, float posYOffset = 0f, float posZOffset = 0f: Vector3 position offset for the sphere related to the space
• string posOffsetCallback = null: use a callback or a field value as the position offset. The value must be a Vector3
• 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.

[DrawLine]  // also draw the lines
[SphereHandleCap(color: "#FF000099", radius: 0.1f)]
public Vector3[] localPos;

[SphereHandleCap(radius: 0.1f)]
public GameObject[] objPos;  // use obj's position
