Jumping

]] Jumping is a form of movement on Roblox. To jump, the player must simply press the space bar, the jump button if you are on mobile, or A if you are on Xbox. After the bar is pressed, the character will go up and then come back down. While coming back down, the character's arms will sway up. It is possible for the game developer to change the jumping, via scripting, as well as changing the animations so the arms don't sway.

You can jump on top of an 11 stud high block normally, with something near 14 studs up with a freeze-high jump, without having to climb up the edge of the block with a jumpower of 50 if you jump up vertically - which is the default jumping height that Roblox sets - this can only be changed with scripts (unless you are on Roblox Studio where you can change it from the properties tab), so that means it'll vary from game to game.

The jumping animation has changed over the years. It used to directly put both arms pointing vertically up when the player jumped. This was changed in October 2013 along with new idle animations and emotes.

Players often jump away from other players if they try to attack them, usually to get away from the enemy quickly (however, it does not make you move any faster). Some players also use shiftlock so they can move backwards. The maximum jump a player can do platform-to-platform is 13 studs, with something near 14 studs with a flick-high jump.

If you delete your legs, there is a chance that you might not be able to jump without resetting.

Manipulation of jumps
In Roblox Studio, a developer has the ability either through script or by manual clicking inside the Studio Explorer to manipulate a person's jumping. Jump has a boolean value and is located in the Humanoid of a player. It can be set to true, but will be automatically set back to false after the jump has been executed.
