- Added option to start the StateTree automatically on BeginPlay - StateTreeComponentSchema: allow to specify which actor class to expect the StateTree to run on (allows to bind to Actor specific data directly) - Fixed FStateTreeReference parameter update on BP instance (the struct gets copied, which cause issues with the delegate handle) #rb Mieszko.Zielinski #preflight 630c70bb0345de4ccf7c8b51 [CL 21685020 by mikko mononen in ue5-main branch]
