Hi,
Should you wish to make use of variables between blueprints and are unable to cast to that blueprint there is a solution.
Make a Blackboard, you can find this in the AI section. For illustration purposes I called mine “GlobalVars_Blackboard”
In any blueprint that you wish to access a “global variable” use the “Add Blackboard Component” and then select your blackboard. You can add your blackboard to as many blueprints as you like but I’m sure there will be some performance drawback (not tested or measured).
From the “Add Blackboard Component” wire the “Return Value” terminal to either a Get or Set Value as Bool / Int / Float / …
You will need a Key Name. Use the “Make Literal Name” and type in the name of the variable and you’re done.
I know this is a devisive topic and I’m not debating whether they should or should not be used (valid arguments for and against) this is simply a “How To” should you want to use it.
