Execute any function by typing on the keyboard (Phaser3)

Things I want to do

When a key is pressed in Phaser3, an arbitrary function is executed.

this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.A);

Within the update statement, you can execute arbitrary code by obtaining the following values from the return value mentioned above.

isDown

However, I think it’s best not to write key events other than actions (such as pause or retry) inside the Update block.

This can be implemented using On as follows:

In most cases, it’s best to call it using Create.

The listener is executed when the Space key is pressed.

        this.input.keyboard.on('keydown-SPACE', listener);

The ‘SPACE’ part of ‘keydown-SPACE’ can be changed to any key. Changing it to ‘keydown-A’ will cause it to execute when the A key is pressed.

A listener is a function that takes an Event as an argument.

You can also write it like this without defining a function:

        this.input.keyboard.on('keydown-SPACE', event =>
        {
            //処理
        });

It is now possible to process input without using Update when a key is pressed.
