Is it possible within a blueprint to have OTHER variables be grayed out (or not) depending on the status of a “main” variable? For example, in the screenshot below I’d LIKE for my “Can Interact?” boolean to determine if the REST of the exposed parameters right below it are even illuminated (available to edit) or not. Because if I have that boolean set to FALSE in my case here, then NONE of the 4 parameters below it matter at all.
you are asking about Editable versus visible:
in C++ you would do this with
UPROPERTY((EditAnywhere, meta = (EditCondition="[VariableNameHere]"))
this will do a rigid binary evaluation
you can do this with non-booleans, but it must be done through string interpretation to boolean (EditCondidtion="[VariableNameHere] == 5") this will evaluate on Editor Tick() but spelling is absolute, and will be runtime evaluated.
that is without going into Details Panel Customization in Unreal Engine | Unreal Engine 5.3 Documentation which is very specific, and has mostly been replaced with Editor Plugins, or Python
for variables declared in Blueprints themselves:
I can’t find anything on this.
