 * Notes
+** making the plane jump
+- input action
+- jump const / variable
+- ONLY at the initial touch of jump, adjust the jump velocity
+
+** add jump
+- create const variable to represent JUMP-POWER
+- add an action input
+  - Project->Project Settings-> Input Map
+  - in the "add new action" textbar enter the action name (jump)
+  - hit the +Add button to the right of the "add new action" field

+  - an event configuration dialog pops up, you can hit the keypress or choose whatever input will activate the action

+** add code to check for the input
+- in ~_physics_process~
+- check for ~Input.is_action_just_pressed("name of action")~
+- and set ~velocity.y = JUMP_POWER~
+  - physics engine will take care of the velocity changing due to gravity and distance
