Object Creator

The Collide Project

Step 1: The Object Creator

Instructions: The Object Creator works a lot like the Microsoft Paint program. You can draw a shape using polygons, rectangles and circles, filled with a color or not. However, note that with Object Creator, the drawing you do is stored as vectorized shapes.

The shapes you create in Object Creator are meant to be put into a little 2 dimentional world in Phase 2, so you have to give them properties, like how much mass they have, where their center of gravity is, and whether they have a positive or negative charge. It's also a good idea not to make the pictures too large or complex, because you'll want to add a few to the World Simulator to watch them interact.

Drawing Tip: Use the polygon (or polyline) tool to draw a rough estimate of what you want. Then use the selection tool to select individual nodes of the polygon. You can drag them with the mouse, or use the arrow keys to move them pixel by pixel.

New Features:

Individual node manipulation for polyline objects
Arrow keys for fine movement
Keypress now terminate polylines (in addition to a double-click)
Tab selects next object
An undo stack
A resize dialog, and the ability to toggle the center of mass "X"
