- Removed unnecessary checks for specific transition (handled in enter state logic) - Added state type to StateTreeState, State, Group, or Linked - StateTreeState property customization hides properties based on type - Allow a state to link to another state - Changed baker binding validation to handle linked states - Added linked state handling in execution context - Updated UI deal with linked states - Updated gameplay debugger to deal with linked states - Moved automatic Root state adding from Editor data to editor open (tests were broken due to extra root state) - Fixed tests and added simple test for linked state - Added meta to tag to state link to allow to select only direct states (no next, etc) - Added counter to track state changes (mainly for debugging) #jira UE-147509 #review #preflight 624beb69637925b5d306d8e7 [CL 19621621 by mikko mononen in ue5-main branch]
