UENUM Circular Dependencies?

[jpalmer999]

Hi,

I am attempting to create a drop-down menu for my blueprints where I can easily set the wanted stat rather than typing it out and potentially making a mistake. However, when I try to do this it returns the following errors. I am still getting to grips with C++ and Unreal so I am a little confused about what the error means.

Any help would be greatly appreciated,

Error: (Line 35) The property “Stat1” references type “StatSelection” but the code generation hash is zero. Check for circular dependencies or missing includes.

Error: (Line 44) The property “Stat2” references type “StatSelection” but the code generation hash is zero. Check for circular dependencies or missing includes.

The Unreal Header Tool (UHT) don’t know what StatSelection is because you declare it further down. Move the declaration for enum class StatSelection above your class declaration class ASpell_PassiveBuff_Master.

Moving the enum declaration into a separate file altogether might be even better if you intend to use it without the ASpell_PassiveBuff_Master class.

Thanks that did the trick.
