Jumpboosting involves entering ragdoll mode during a jump. It allows you to jump higher and further.
How to Jumpboost
Step 1 – Run forwards, sprint and jump. Make sure to have enough room to jump before you enable ragdoll mode.
Step 2 – Enable ragdoll mode just before the peak of your jump. This will give you a small speed boost.
Step 3 – Disable ragdoll just before you hit the ground in order to land on both feet, otherwise you will fall and have to get up.
