Godot Input Event Example

I want to do a simple board game. Lots of things, I don’t really understand, example the input events. I read the Godot documentation on Input Event but they didn’t provide any project example besides the code.

For beginner, it is not straight forward. So I share the project Input Event example based on the Godot documentation example.

Steps To Do

1. Create Godot Project

2. Create New Input Map

– Click Project -> Project Settings

– Choose Input Map tab

– Find ui_right and choose the right key on your keyboard
– Then click OK
– Do the same with ui_left

3. Test it, by pressing the keys on your game.

– The text will appear on the output screen

godot - output screen — godot – output screen

Add Custom Input Map – Mouse Left Button Click

1. Go to project -> Project Settings

2. Type ui_mouse_left_button_click (you can give any name)

godot - add new input map — godot – add new input map

3. Click Add

4. Add left button event to the Input Map

godot - mouse left button click input map — godot – mouse left button click input map

godot – added mouse left button click

Godot 3.2.3 Inheritance GDScript Call Parent Function

Lets say you want to have two GDscripts where the ChildScript.gd will call ParentScript.gd.

From there, you want the ChildScript.gd to call its parent function.

Create Class Inheritance

You first create inheritance in GDScript by calling “extends”.

extends "res://gdscript-filename.gd"

#example
extends "res://Parent.gd"

extends "res://gdscript-filename.gd"

#example

extends "res://Parent.gd"

Call Parent Function . Use dot “.” to call parent function

#function example, where child calls parent function
.getText()

1 2	#function example, where child calls parent function .getText()

Download Godot Project Example

In this example, when “Press Me” button is clicked. The label will change to “Parent Child” where “Parent” is return value from parent function while child is from child function.

godot-3-2-3 inheritance call parent function

You can download here the project example.

Godot Button Signal Tutorial

I’m still new to games development using Godot engine.

I follow the button signal tutorial on Godot website. I created the project for easy reference for others because at the website they don’t provide the Godot project that you can immediately play.

Full GDScript from the tutorial

# Declare member variables here. Examples:
# var a = 2
# var b = "text"


# Called when the node enters the scene tree for the first time.
func _ready():
	#pass # Replace with function body
	get_node("Button").connect("pressed", self, "_on_Button_pressed")


# Called every frame. 'delta' is the elapsed time since the previous frame.
#func _process(delta):
#	pass


func _on_Button_pressed():
	# pass # Replace with function body.
	get_node("Label").text = "HELLO!"

# Declare member variables here. Examples:

# var a = 2

# var b = "text"

# Called when the node enters the scene tree for the first time.

func _ready():

#pass # Replace with function body

get_node("Button").connect("pressed", self, "_on_Button_pressed")

# Called every frame. 'delta' is the elapsed time since the previous frame.

#func _process(delta):

# pass

func _on_Button_pressed():

# pass # Replace with function body.

get_node("Label").text = "HELLO!"

Download Godot Button Signal Project

You can download the button signal Godot project here, if you want to run the tutorial.

In case the button signal tutorial is broken link for what soever reasons, I have converted the web page into PDF.

Hope it helps beginner games developer like me.

Apple Macbook Pro M1 MacOS Big Sur – Missing xcrun after MacOS Update

I always face missing xcrun when I use command “git pull” after MacOS update where the OS will update xcode.

apple macbook pro M1 - missing xcrun — apple macbook pro M1 – missing xcrun

To solve this problem just install back the xcode-select via the command line.

xcode-select --install

1	xcode-select --install

A window will appear whether to continue to install. Just click install.

apple macbook pro M1 - install xcode-select — apple macbook pro M1 – install xcode-select

It takes around 5 minutes to download the file.

After installation, run again the “git pull” . This time it will work.
