How Can I Use New Maps Gears 4

From my previous projects one of the master suggestions that players asked for was to implement central/button bindings and an accompanying controls bill of fare.

Why bother?

Hard coded keys or buttons limits the gameplay of some players as they prefer their own custom layouts. Swapping the spring input, the sprint input or the crouch input fixes this for nearly.

Giving your players access to this feature will amend the quality of life your players will have throughout the entire experience.

Improving the User Experience

The outset stride to having fully bindable fundamental inputs is to use Input Deportment and Input Axes for your game.

These features can inform the engine exactly which feature y'all wish to rebind e.g. Shoot or Reload. Saving this to the Input configuration file is then easy so remembering your custom settings subsequently your players reload their games.

Finding the Input Settings Window

To observe the input settings window, click on Edit and find the Projection Settings option.

The Project Settings window volition open up upwardly and look like this:

On the left manus side we tin see all of the settings we can change in our project. Input contains what nosotros need.

On the right section of the Project Settings window we volition now see all of the input settings that we can change in our project.

At the meridian you tin meet the ii lists for Input Actions and Input Axis under the Bindings category

Action Mappings

What are Action Mappings?

Action mappings are inputs that only output execution pins. Triggering these events tin can run new lines of design code.

Examples of Action Mappings

Action Mappings are perfect for single fire events such as reloading, jumping, crouching or shooting. Well-nigh inputs should use Activeness Mappings.

Creating your Activeness Mappings

To see the list of current Action Mappings, press the triangle to the left of the Action Mappings text.

Here we tin can see all of the Action Mappings that my project uses. These are the defaults that come up with the FirstPersonShooter template.

To create a new Action Mapping press the + icon next to the Action Mappings list.

Requite the new Action Mapping a name that relates to what you want to use it for. In this example I named mine LightToggle as I am going to use this input for toggling lights in my level.

From hither you tin can now click the driblet down box that current says None and select the fundamental that you want this Action Mapping to utilise.

Shift, Control, Alt and or Command have modifier boxes to the correct that tin also exist ticked to make your input only piece of work if they are pressed at the same fourth dimension.

To add together multiple input keys you can printing the + symbol next to the name of the Action Mapping. This adds one actress central that will cause this event to trigger

Adding Functionality

At present your Action Mapping's are fully setup. Type the proper name of your Mapping inside your character or pawn pattern event graph to become an event.

To use your new mapping in a non character or pawn design, you will need to utilize the enable input node on brainstorm play for that player.

This is due to actors non receiving input events by default

This fires when your custom input is pressed or released.

Input Action Consequence Testing

To make sure that this input works I have attached two print string nodes to the InputAction. This prints "Calorie-free Toggle Pressed" when LightToggle input is pressed and "Light Toggle Released" when LightToggle is released.

Axis Mappings

What are Axis Mappings?

Axis Mapping'due south outputs a single execution pin every frame and also outputs a float value that is set by specific keys/buttons, command sticks or mouse inputs.

Different code can be run on the Axis value as each axis value is assigned is set to a different key.

Examples of Centrality Mappings

I example of this is the start person character template movement code.

Pressing no keys outputs 0.

Pressing the A key sets the float output to -one and moves the player left.

When the histrion presses D the role player moves right due to the float output beingness one.

This output sets the calibration of the add together motility input office.

The axis value is used for the mouse input to command the camera of the get-go person grapheme.

The horizontal move of the mouse is converted to a bladder based on the direction and speed of the mouse and is sent to add controller yaw input to rotate the character.

Creating Axis Mappings

To see the list of electric current Axis Mappings, press the triangle to the left of the Axis Mappings text.

Here are all of the Axis Mappings that my project uses. These are also the defaults that come with the FirstPersonShooter template.

To create a new Axis Mapping press the + icon next to the Axis Mappings listing.

Axis Mappings contain a float which outputs when your specific fundamental is pressed.

I take assigned O to -1 and P to one in my Axis Mapping named KeyAxis.

Calculation Functionality

Axis Mapping are now setup. Typing the name of the newly created Mapping, within of whatsoever blueprint upshot graph, shows an issue that will burn your custom bladder value when your specified input is pressed.

Equally a effect nosotros can now see 2 different pattern nodes when looking for your InputAxis.

The offset in the list gives you the result execution pivot that fires every frame and the output float called Axis Value.

The second in the listing gives you just the output float.

Input Axis Event Testing

To exam, add a impress string node to the execution pin of the KeyAxis event. Set up the string value to the Axis Value from the output float from the effect.

Without pressing O and P the impress outputs 0 every frame.

Holding O prints this result:

Holding P prints this effect:

Decision

Unreal Engine's robust input at present is fully working. Therefore, in the future, input can exist rebound to different keys based on the users preference.

Hard coding input causes difficulty downward the road with every blueprint. Hard coded binds cannot exist inverse during runtime.

It's worth getting into the addiction of settings these up for every input you want to utilize for your games.
