Errors
- Error, BEGIN OBJECT: Missing class in subobject/component definition: Begin Object Class=class name Name=object name
- Error, Cast from 'class' to 'class' will always fail
- Error, Invalid property or function call on a dynamic array
- Error, Not allowed to use 'config' with object variables
- Error, Could not load existing package file 'package path'
- Error, 'Ignores': 'ExecuteWhatToDoNext' is not a function
Interfaces
- Error, Failed to find DependsOn class 'interface name' while parsing 'class name'
- the Implements modifier in the class declaration contains an incorrect interface name value.
- Error, Implementation of function 'function name' conflicts with interface 'interface name' - different number of parameters (2/3)
Bad or missing expression
- Error, Bad or missing expression in 'If'
- a function in an if statement does not return a type.
- Error, Bad or missing expression in Call to 'function name', parameter number
- Error, Bad or missing expression for token: function, in 'Return'
- Error, Bad or missing expression for token: variable, in 'If'
- to note in this case the variable was an actor reference.
- Error, Bad or missing expression after '+': 'variable name'
- + being an incorrect operator usage?
- Error, 'type' conversion: Bad or missing expression
Missing
- Error, Missing 'function'
- declared a function modifier without a function, defined a function type before function.
- Error, Missing ')' in 'foreach array'
- the variable inside the brackets of a foreach loop is not defined.
- Error, Missing ';' before 'variable name'
- the variable you are trying to access through a typecast is not defined.
- Error, ImportText (struct): Missing closing parenthesis:(member1='value',member2='value'))
Static Functions
- Error, Can't call instance functions from within static functions
- Static functions can only call other static functions.
- Error, You can only access default values of variables here
- tried to assign a non default variable a value, using a non default variable in a statement, assigning a variable a value from another that isnt a default variable. There are instances where you can access non default variables in Static functions, if the variable is part of the function definition, a local variable.
Mismatch
- Error, Type mismatch in Call to 'function name', parameter number
- Error, Type mismatch in '='
Warnings
- Warning, 'variable name' : local variable used before assigned a value
- a variable is referenced before it is assigned a value, which means it'll return the default value for that type, whether that is what you are looking for or not. This could be conditionally incorrect, the compiler doesnt check to see in which order things are carried out so it could infact be wrong, hence only a warning.
- Warning, 'variable name' : unreferenced local variable
- a variable is declared within a function and never assigned a value.
- Warning, Unresolved reference to Class 'class name'
- Warning, function: Missing return value
- a function with a return type has no 'return'.
- Warning, ObjectProperty Engine.MeshComponent:Materials.Materials: unresolved reference to 'object'package.group.object
- Warning, Invalid property value in defaults: property=value
- a property in the defaults is not a defined variable.
- Warning, Using a non-qualified name (would have) found: object package.group.group.name
- Warning, Unable to parse parameter value in defaultproperties array operation: array<struct>.add((member1='value',member2='value'))
- Warning, Unresolved reference to object
- Warning, friendly operator name_TypeNameTypeName: Missing return value
- This is similar to function not having a return value but is the operator version, UScript supports operator overloading so the 'friendly operator name will be a reference to a table within the engine $ being Concat as an example.
Failure
- Failed to load 'object package.group.name': Failed to find object 'object package.group.name'
