fix(cpp): UE 5.6 compatibility for UAnimStateNode result-node lookup - #62
Merged
Conversation
UAnimStateNode::GetResultNodeInsideState() was added in UE 5.7, so the state-machine builder failed to compile on 5.6 (C2039). Guard it with an engine-version macro: use the official API on 5.7+, and on 5.6 (and older) find the state result by scanning the state's bound graph for the UAnimGraphNode_StateResult. Verified: BuildPlugin succeeds on UE 5.6, 5.7, and 5.8; the 5.7+ path is unchanged.
