This page explains how to properly assign multiple inputs and the control expression syntax in the input configuration dialogs.
Buttons
| Detect | Wait for input from the selected device, and highlight the corresponding input in the list. |
|---|---|
| Select | Copy the selected input name into the control expression field. |
| | OR | Copy the selected input name into the control expression field, with "|" prepended. |
| & AND | Copy the selected input name into the control expression field, with "&" prepended. |
| ! NOT | Copy the selected input name into the control expression field, with "!" prepended. |
| + ADD | Copy the selected input name into the control expression field, with "+" prepended. |
Syntax
| Token | Explanation | Example usage |
|---|---|---|
| ` | The backtick is used in cases where the expression is ambiguous. | Button 1 results in a syntax error, because the expression is ambiguous.
Adding backticks around the button name makes it able to be parsed correctly: |
| & | The expression is true if both the LHS and the RHS are true. | `Button 1` & `Button 2`
The virtual controller button will be pressed if and only if both Button 1 and Button 2 are pressed. |
| ! | Negates the following expression's value. | !`Button 1`
The virtual controller button will be pressed if and only if Button 1 is not pressed. |
| + | The expression value is equal to the LHS value and the RHS value summed up. | `Axis 1+` + `Axis 2+`
|
| ( | The left parenthesis is used to open an expression group. | (`Button 1` & `Button 2`) | `Button 3`
The virtual controller button will be pressed if both Button 1 and Button 2 are pressed, and/or Button 3 is pressed. |
| ) | The right parenthesis is used to close an expression group. |
