How to Calculate Jump Force in Godot
You have a character that can jump in your game, either in 2D or 3d.
But when you press the jump button, an arbitrary amount of jump force is applied to the character's y velocity, moving them upward.
But you want your character to be able to jump to a specific height, so how much force should you apply to the character to reach that height?
Start by exporting a private variable for the character's jump height.
Next, change the jump force from a constant to a private variable.
Then in the ready function, calculate its value using a mathematical formula:
_jump_force = sqrt(abs(_jump_height * gravity * 2))
In 3D, you'll simply be able to set the character's y velocity to the jump force, since positive is up.
In 2D, you'll need to set the character's y velocity to the negative of the jump force instead, since up is negative.
