Day 1: Project Setup

Day 2: Basic Movement

Day 3: Fluid movement and Jump

• Always go for tight jump and movement controls
• Add 2-3 frames of acceleration
• If Jump is floaty, dramatically increase Jump speed and Gravity
• Choose frame independent Lerp
• Jump should be variable (When just pressed and when held)
• Jump should be around 3 tiles of height

Day 4: Auto-Tiling, Camera follow and smoothing

• Added Frame independed Lerp for camera smoothing
• Jittery in "Viewport" Window mode
• Use this tutorial to implement a better camera follow with smoothing

Day 5: Animations, Character orientation and Coyote timer

• Make sure to store is_on_floor() before move_and_slide() as it changes is_on_floor() internally
• Check if character "was" on floor and !is_on_floor() to enable Coyote timer
• Enable jumping if is_on_floor || !$CoyotoeTimer.is_stopped()

Day 6: Added Double Jump

• When is_on_floor() is true, enable the double jump

	if(move_vec.y < 0 && (is_on_floor() || !$CoyoteTimer.is_stopped() || enable_double_jump)):
		velocity.y = move_vec.y  * max_jump_speed
		if(!is_on_floor() && $CoyoteTimer.is_stopped()):
			enable_double_jump = false
		$CoyoteTimer.stop() #without this, player can't double jump if coyote timer is high

• if(!is_on_floor() && $CoyoteTimer.is_stopped()): will check if player has already double jumped
• Stop the Coyote Timer right after to avoid not being able to double jump when Coyote timer is high
