Member Function Documentation

ScopeResolver* ObjectResolverObject::GetScope ( VarSpriteGroupScope  scope = VSG_SCOPE_SELF,
byte  relative = 0 
)
inlinevirtual

Get a resolver for the scope.

Parameters
scopeScope to return.
relativeAdditional parameter for VSG_SCOPE_RELATIVE.
Returns

On the first call, the town scope is created (if possible).

Returns
Town scope, if available.
