[Lập Trình Game] Display FPS for games using Godot Engine

FPS (frames per second) aka frames per second. The more frames your computer displays in a second, the smoother the game will be. FPS depends on network speed and computer hardware. To display the FPS of the Game programmed by you with Godot Engine, please follow the instructions below.

Display FPS for games using Godot Engine

FPS

First of all, you have to create 2 Nodes for yourself CanvasLayer and label. Label is a child node of canvaslayer

And I renamed the label -> fps label

You create yourself a script in Node World

In the declaration section, you declare yourself as follows:

onready var fps_label = get_node("CanvasLayer/fps_label")

get_node() is to get your node address

onready var is to declare a variable that is always available eg like this:

• The normal var is a gun without ammo
• Onready var is a gun that is ready to be loaded
• Declare var in _physical_process then only when physical_process works then var it works

Add yourself a function func _process(delta):

_process(delta): is the function called on every idle frame

_ physical _process: is 1 function call on every physical frame

You can look it up in godot’s documentation: https://docs.godotengine.org/en/3.0/classes/class_node.html#class-node-process

And if you use the function _process(delta): you need to enable it in func _ready function with command set_process(true)

And back to the main part.

LIVE _process you guys type yourself

func _process(delta):

fps_label.set_text("FPS: " + str(Engine.get_frames_per_second()))

After typing and running the game, the fps will be displayed

Note: You have to change the position of the label if you want to see the fps

And you can also print FPS to debug by the following way

Project > Project Setting > Find FPS > click Debug Settings > Click Print FPS On > run the game and notice the debug will see the fps displayed
