Polygons
Level editor tool
Object type	Polygons (polly)
Available in Happy Wheels since version	1.55

Polygons are types of shapes that can be created with the polygon tool in the Level Editor. They were added to the game on January 10th, 2012 with the V1.55 release. They are custom shapes that can be created by dragging lines to lines by clicking your mouse. Eventually, at the end, the last line must hit the beginning point of the first line. They've got the same options as shapes, interactive and uninteractive, fixed, not fixed, etc., and they've got an almost unlimited amount of width and height, the smallest possible size for an actual polygon is only 2x2px, unlike shapes, which have a limit of 5 - 5000px of width/height. The largest is 20000x10000px, which would take up the whole screen. To undo a vertex placement while making polygons, press and hold ctrl (cmd on a mac because ctrl will result in a right click), and left-click. While making a uninteractive polygon, you can also hold shift then left click while making a polygon which will leave the thin lines instead of filling in the shape. Polygons also have an opacity option. This affects opacity (or transparency), in which 0 is invisible and 100 is completely opaque.

Interactivity

Creating polygons has its differences depending on if they're interactive or not. Interactive polygons have generally stricter limits, and is therefore harder to create your desired result. Interactivity can't be toggled on/off on polygons when they're already made, unless you change the xml of the level, which usually results in bugs and performance problems.

Interactive

An interactive polygon has a limit of 10 vertices (lines) and its points can only be placed clockwise. Vertices can also not be as small as non-interactive polygons.

Non-interactive

Non-interactive polygons have a 50 maximum vertices, and no restrictions on placements. They've got more options like leaving single lines without a shape fill. Lines can also be smaller.

Trivia

• Non-interactive blocks have no interactivity options, and cannot be changed from non-interactive to interactive and vice versa.
• The editor counts down how much is left after each line, even though vertices are corners/points on a shape.
• If something with polygons is copied from one level to another, it will appear normal in the editor, but when you test it, the polygon will mutate and glitch out. It may also affect other polygons in the level. This was fixed in the v1.64 update.
• You can draw a thin, non-interactive line by making one line, hold shift and click.
• The first vertex is counted twice (one for the start of the shape, and once for the end)
• A scalene triangle (a triangle in which all three sides are of different length) can be made with the tool, but not with the shape tool.
• Sometimes when creating an object with the tool, if you select your creation you made, invisible lines will be selected as well, even when you didn't place them here.
• It is possible to make an uninteractive "shape" with either its width or height 0. Simply make a line completely vertical or horizontal then click while holding shift, but it is impossible to make an uninteractive shape with both the width and height 0.
