Some notes and issues when trying to clamp the rotation of a camera in Unity. All the code was put on a script assigned to a controller that controlled the camera view. Used the Simple Touch Controller from the asset store.<\/p>\n\n\n
Problem trying to clamp EulerAngles<\/strong><\/p>\n\n\n It appears that the following code does not work as EulerAngles expects a value from 0-365.<\/p>\n\n\n\n Extra debug info<\/strong><\/p>\n\n\n\n Code to clamp rotation<\/strong><\/p>\n\n\n\n You have to do some math to take the value from 0-365, then translate it to -90 – 90 so it can be clamped properly <\/p>\n\n\n\n The following links were helpful.<\/p>\n\n\n\n https:\/\/gamedev.stackexchange.com\/questions\/120500\/using-mathf-clamp-in-vector3-to-restrict-object-drag<\/a> https:\/\/stackoverflow.com\/questions\/26682155\/using-mathf-clamp-in-unity-for-boundries<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Some notes and issues when trying to clamp the rotation of a camera in Unity.
