Cease Nonsense

prefer-udim2-shorthand

Replaces new UDim2(...) with UDim2.fromScale(...) or UDim2.fromOffset(...) when the other half is zero.

Rule details Suggestion

Section titled “Rule details ”Suggestion

The rule checks new UDim2(scaleX, offsetX, scaleY, offsetY) calls with exactly four arguments.

  • If offsetX and offsetY both evaluate to 0, it reports UDim2.fromScale(scaleX, scaleY).
  • If scaleX and scaleY both evaluate to 0, it reports UDim2.fromOffset(offsetX, offsetY).

It can evaluate numeric literals, identifiers, unary + and -, and simple arithmetic with +, -, *, /, and %. Mixed scale and offset constructors are left alone.

Examples

Section titled “Examples”
Incorrect 
new UDim2(1, 0, 1, 0);
new UDim2(0, 100, 0, 50);
new UDim2(x + 1, 0, 1 - y, 0);
Correct 
UDim2.fromScale(1, 1);
UDim2.fromOffset(100, 50);
UDim2.fromScale(x + 1, 1 - y);


new UDim2(0.5, 10, 0.5, 10);
new UDim2(0, 0, 0, 0);

What gets skipped

Section titled “What gets skipped”
  • constructors with fewer or more than four arguments
  • constructors where the zero side cannot be evaluated
  • unsupported expressions such as bitwise operators or string literals
  • mixed scale and offset values
