Make the jump feel better: limited to 1m and less floaty:
add an export var to represent the jump height
add an export var to increase fall speed
add a variable to represent gravity as a float
In the physics process function
In the jumping code we use the formula:
Max Height = Square root of (jump_height x 2 x gravity)
If you want to increase mouse movement speed
increase the mouse_motion multiplier as shown
Test this by adding stairs
Add a new StandardMaterial3D
Set the Albedo to an Orange Colour
Change y position to 1.0m
Change z position to -6.0m
Repeat the steps for Platform3
If you add another platformer and make it higher than 1m, the player will not be able to jump to reach it
