hey , so im kinda new to C++ and Unreal Engine 5.0.2 and recently i have been trying to add a new C++ class RadialForceActor called Explosion but every time i try , it throws off this error :
and the output log :
error for copy :

CompilerResultsLog: Error: C:\Projects\UnrealEngine\TestProject\Binaries\Win64\UnrealEditor-TestProject-2104.dll : fatal error LNK1120: 5 unresolved externals
building from ide throws the same error
and i wasn’t able to find a fix for this
so i would be happy if someone helped me to solve this issue
