Lesson 4: Creating the player

In the last part of this chapter, you should use the compositing pattern by exposing the camera variable like this.

@export var camera: Camera2D

After that in the main.tscn you must assign the camera2D to the camera variable of the Player.

The player component must be not know where the camera is.

I was under the impression that it was a bad idea to scale anything that had a collision shape in it. Is this no longer the case in GD4?

In Godot 4.1, there is no “Loop” slide button to disable the looping animation. It is now the two arrows pointing to each other, just to the left of the number of frames per second.

Also, in order to get your raptor to run by default, you have to click the “A” inside of the arrow (next to the “Loop” icon) to set an animation as the default.

For the jumping code section, I recommend using the “was_jumping” variable to easily see if the current jump should be a double jump. Also, this allows you to directly code the pitch without requiring a variable.

It should be noted that this approach of hard-coding the values assumes that the player will only have two jumps; or, if more jumps are available, then all but the first will be considered “double jumps”, no matter how many occur.

	if was_jumping:
		sprite.play("double jump")
		jump_sound.set_pitch_scale(1.3)
		jump_sound.play()
	else:
		sprite.play("jump")
		jump_sound.set_pitch_scale(1.0)
		jump_sound.play()
			
	jumps_remaining -= 1
	was_jumping = true
	velocity.y = jump_power

When you referred to the A button next to the trash can icon, on the left hand side of the sprite frames panel did you mean the auto play on load button?

Hi, I had issues with sound playing only on the second jump. I tried to look at the code in the Github but I couldn’t find the one for sound. I eventually had to add an extra line just to get it to play a sound twice but it wont increase in pitch. Could you please have a look for me and tell me where I went wrong? Thank you.

			jump_sound.set_pitch_scale(jump_pitch)
			jump_sound.play()
			jump_pitch = 0.2

In the end I had to hard wire it to get it to work. Another student created the code if was_jumping: sprite.play(“double jump”) jump_sound.set_pitch_scale(1.3) jump_sound.play() else: sprite.play(“jump”) jump_sound.set_pitch_scale(1.0) jump_sound.play()

this one worked. Not sure why when I enter the code in the video the jump sound only makes a sound when I hit the spacebar on the second jump. I tried everything from retyping each line of code 3 times and re running it after each line. It may be an issue with the newest version ?

thanks

I am at about 7 minutes just after completing the player. The player doesn’t show up when you switch to the main world node. And there is a warning icon next to player saying it has no shape?

Followed tutorial exact. Even redid a few times!

For anyone else who got stuck with an error “Identifier “jumps” not declared in the current scope”, and if your player is able to jump an infinite number of times, the little preview of the script page on the top right is cutting off the full line (e.g. at 20:20 in the video)

Instead of

if Input.is_action_just_pressed("jump") and jumps:

it should read

if Input.is_action_just_pressed("jump") and jumps_remaining > 0:
