To see the list of current Axis Mappings, press the triangle to the left of the Axis Mappings text. The horizontal movement of the mouse is converted to a float based on the direction and speed of the mouse and is sent to add controller yaw input to rotate the character. The axis value is used for the mouse input to control the camera of the first person character. This output sets the scale of the add movement input function. When the player presses D the player moves right due to the float output being 1. Pressing the A key sets the float output to -1 and moves the player left. One example of this is the first person character template movement code.

Axis Mappings What are Axis Mappings?Īxis Mapping’s outputs a single execution pin every frame and also outputs a float value that is set by specific keys/buttons, control sticks or mouse inputs.ĭifferent code can be run on the Axis value as each axis value is assigned is set to a different key. This prints “Light Toggle Pressed” when LightToggle input is pressed and “Light Toggle Released” when LightToggle is released. To make sure that this input works I have attached two print string nodes to the InputAction. This fires when your custom input is pressed or released. This is due to actors not receiving input events by default To use your new mapping in a non character or pawn blueprint, you will need to use the enable input node on begin play for that actor. Type the name of your Mapping inside your character or pawn blueprint event graph to get an event. Now your Action Mapping’s are fully setup. This adds one extra key that will cause this event to trigger Adding Functionality To add multiple input keys you can press the + symbol next to the name of the Action Mapping. Shift, Control, Alt and or Command have modifier boxes to the right that can also be ticked to make your input only work if they are pressed at the same time. In this case I named mine LightToggle as I am going to use this input for toggling lights in my level.įrom here you can now click the drop down box that current says None and select the key that you want this Action Mapping to use.

These features can inform the engine exactly which feature you wish to rebind e.g. The first step to having fully bindable key inputs is to use Input Actions and Input Axes for your game. Giving your players access to this feature will improve the quality of life your players will have throughout the entire experience. Swapping the jump input, the sprint input or the crouch input fixes this for most. Hard coded keys or buttons limits the gameplay of some players as they prefer their own custom layouts.
