Topic, Level Editors - A handbook

The line tool. The most important tool in the editor. It's used to draw the lines the levels are made of, and edit previously placed lines.
To create a new line, select the line tool. Then click once, to define the starting point of your line. Next time you click, you define the direction of the line.
The third time you click, you define how curved the line will be. Once you've done this, the line will turn white. This means that you're ready to end the line. If you want to add more segments, feel free to draw them on, but if you want to end the line, click on the line.
To edit an earlier placed segment, hold your cursor close to the ending point of the mentioned segment. Once you've positioned it properly, hit CTRL twice.

This tool does what is says. It lets you delete the objects or lines you've placed. If you choose this tool, you'll notice your cursor turning into a small red cross. If you click on an object or a line, it will be removed. If you hold and drag, you'll form a red square. If you release the cursor, any objects inside the square will be deleted.

The move tool simply moves objects. You're able to select multiple objects, the same way as the delete tool. A blue outline will show what objects are selected. Click and drag one of these objects to move them.

The edit tool is complex, compared to the other tools. It allows you to edit the attributes of the selected item, but the attributes change from object to object. A blue outline will show what objects are selected.

You might have noticed the dark blue grid in the background of the editor. Every object you place, or line you draw will snap to this grid if it's turned on. This feature can be very good, and a great help, but sometimes you want to draw fine details. You can change the grid in two ways: You can either hit G to turn it completely off, even though I will not recommend this for longer periods of time. The second way is to edit the grid size. This will either decrease or increase the size of the grid, and make the objects/lines snap on to the smaller/bigger grid instead. The grid options are located in the lower left corner

The info bubble is simple. It's a small buble, that can be chosen to either be visible, or invisible (Using the edit tool). When the player touches the info bubble, a message will be displayed on the screen. This message can be edited in the info bubbles attributes.

The switch itself is quite simple. It's an invisible circle, used to activate path's when the player touches them. There's no indication of where they are for the player. They are completely transparent in-game, and non-solid.

The boulder is an object, affected by gravity. It's exclusive to Rolling Turtle. Using the edit tool, you're able to choose the size of the boulder, and when it should start being affected by physics. This allows for great traps, or to have it freeze in the air. Path's can move boulders around too - as long as they aren't started yet.

The path is the most advanced object in the game. It's what's used to move objects or lines, and experimenting with it can lead to new gameplays. I could easily make a whole topic about path's, but I'll try to keep it short. If you want to select what objects/lines the path should move, use the edit tool and click on the path. Once you're in the path's attributes, click on the lines/objects and they will get the blue outline. You're able to choose when the objects/lines should start moving, by editing the "Start" option. You can choose when it should end, by editing the "Stop" option. Furthermore, you should click the small green "+" sign to add a new note. If you hit it multiple times, it will create more notes which you can then move around. These notes will define the path the objects should move along. Try things out, experiment, and you should be able to learn everything else that is to know about path's!
