Jump Lab
Start from a preset or tune every number behind a jump, compare two configurations on the same recorded input, and compare posture on an identical physical path.
Three tools live here. The first lets you start from a preset or open up every parameter, change the numbers behind a jump and log what each change actually does. The second lets you record one real jump as configuration A, then edit the numbers into configuration B and replay the exact same input against both. The third holds the physical path fixed and only changes how the character looks in the air — because posture is a cosmetic choice, never a physics one.
Gravity and launch speed
Who is really in control while you're in the air? Start from a preset or open the advanced parameters below, then jump — each change applies to your next jump, never mid-air, and every completed jump is logged below with the exact numbers it used.

Compare two configurations, same input
Adjust the parameters below and press Record, then perform one jump — that becomes configuration A, keystroke for keystroke. Change the parameters again to define configuration B, then press Replay: both bodies see the exact same recorded input from the same starting point, so anything different between them comes from the numbers, not from how the trial was played.
Adjust the parameters below, then press Record and perform one jump to save configuration A.

Same path, different body
Body A and Body B share the exact same recorded jump — identical takeoff, apex and landing. Only their arm swing, leg tuck and landing compression differ, so any difference you see is posture, not physics.
