You can make any Actor face to the left by adding the following code in it’s code window. Setting the rotation style to left-right ensures that it does not turn upside down.
{“func”:“registerFlagTrigger”,“next”:{“func”:“blockMotionRotationStyle”,“values”:[{“type”:“choice”,“value”:“left-right”}],“next”:{“func”:“blockMotionPointTowards”,“values”:[{“type”:“string”,“value”:“left edge”}]}}}
