Popular user-made creations are common user-made contraptions, hazards, mechanics and other various special items consisting of multiple objects and tools (usually a pin joint) already found in the Level Editor. Because they are user-made, none of these creations can be found in the Level Editor, and must be manually made. There are, however, some exceptions as to what counts as a custom creation, both artwork and vehicles do not count as a user-made contraption, as the first is usually aesthetic, while the latter is a feature in the game. Only physical objects which change the playing experience are listed.
Chompers (also known as snappers, scissors, and clappers) consist of two interactive items (often blade weapons) connected to a pin joint on the back ends. Unless the two interactive items are not blade weapons, as soon as one latches to the player, it is usually a matter of seconds until they end up easily ripping apart a character, otherwise its only threat is crushing a character. Several user-made levels use them, including the most recognizable use in the featured level, --=|Obst. Course|=--, and various other levels, usually consisting of "Justin Bieber" (Irresponsible Son or an Elf) getting thrown into a pit of chompers.
A gear is a group, which consists of a very dense circle in the middle with parallel rectangles around it. A pin joint is placed onto the center of group. Crushing gears use two of the same gears and pin joints to crush a character when the player falls in between the gears. The pin joints' torque value is usually set to a high number (for example, 30000), and the motor speed is both set to a low rotating speed, and set to an absolute value of each other.
A cushion is used to soften the landing of a character to prevent him or her from being injured or dying from high falls. Cushions are commonly used in quiz levels where Segway Guy falls down after answering a question correctly onto a cushion.
A cushion can be made in two ways:
- A simple stack of 0.1 density rectangles.
- A single rectangle with crossing jointed rectangles below it.
ElevatorAn elevator consists of a group containing wide rectangle with a thin and long rectangle directly below it jointed to a long collision 3 rectangle that is also jointed to a big collision 3 circle jointed to the background. The pin joint that pins the circle to the background usually has a low motor speed to keep the character from either having a hard time getting entering, or getting launched into the air too much. They are used to allow things to be lifted or lowered to different heights.
Jet PackJet Packs are simple vehicles that consist of a few non fixed shapes that fit around the player and jets that are either automatic, or activated by pressing space. Some levels involve the player flying through obstacles such as spikes using a Jet Pack. A jet pack can be made by placing some non-fixed blocks around the character, grouping them and setting them as a vehicle, then place a jet so it is overlapping the vehicle, and attach the pin joint so the jet and the vehicle are now attached to each other. Set either spacebar, CTRL, or shift to 2, which will make the jet fire once the selected key is pressed, and check 'fixed angle' on the jet, which will not allow the jet to turn.
Piston/CrusherPiston/crushers are used in levels to crush, or push a character. Crushers are often used in Meat Factory levels. A piston/crusher can be made by placing down an unfixed circle, a thin rectangle next to it, a wider rectangle next to the thin rectangle, and two fixed rectangles next to the wider rectangles. Attach pin joints to where the thin rectangle and the circle overlap, and where the thin and wide rectangle overlap.
