Variable is not blueprint writable

Development Programming & Scripting Blueprint
1

Hello,

I’ve been getting this error that I’ve never seen before. It seems to affect local variables in functions. Whenever I compile I get this fatal error:

“[VariableName] is not blueprint writable.
[VariableName] is not blueprint visible (BlueprintReadOnly or BLueprindReadWrite). Please fix mark up or cease accessing as this will be made an error in a future release”

I don’t know what this error means. I have not done anything special when creating the variables, and I can’t see a place where I could set a “visible” or “writable” or “read only” parameter.

Is your variable have the same name as the function output name?

I don’t think so. It was a while ago and the issue stopped happening as suddenly as it appeared. I don’t believe I changed anything in the way I work with functions.

You are right, this is caused because input or output variable name is same as local variable

Had the same issue, solved it by prefixing the local variable name with an underscore.
That way, the variable name looks the same in the BP editor, but removes the error.
