Variable is not blueprint writable

Development Programming & Scripting Blueprint

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
