I created a new action named BladeAction and keyframed the influence slider of a Shape Key I couldn't use the action in the Logic Nodes / Action Actuator. Then I examined the action in the NLA and Action Editor it looks like that:
A KeyAction strip has been created by Blender and is not accessible from the Action Editor the BladeAction has no keyframes and cannot be frozen (snowflake icon). I can use the KeyAction from Action Actuator but I'm somewhat confused why this behaves like that.
Why are no keyframes in the Action created by me? Why does Blender create an Action Strip* which cannot be edited?
[.blend] is already linked here: Can gravity be disabled for a single object in the BGE?
