The Collide Project

Step 2: The World Simulator "Collide.exe"

  

This is where the fun begins. After placing a few objects around the screen, play with the object and world parameters to make them interact with each other in different ways. If you turn collisions on, then when two objects collide, they react in one of three random ways:

1. They might bounce off each other.
2. One might break into two smaller pieces.
3. One might "gobble" the other one up. That is, they might merge.

Step 1:   Select one of your objects from the Object menu.

Step 2: Select the "Add" tool and place the object by clicking around in the document.

Step 3: Change the World Properties, like how much gravity there is, and whether same objects attract or repel. Be sure to tweak these values, it makes the world much more interesting. Change the Object Properties (size, velocity, etc.) too. The following table shows the mouse shortcuts for modifying an object.

Select Tool	Add Tool	Action
Right Button Drag	Left Button Drag	Change the velocity of the object.
Shift + R-Drag Horizontally	Shift + Drag Horizontally	Change the rotation angle of the object.
Control + R-Drag Horizontally	Control + Drag Horizontally	Change the size of the object.

Step 4: Press the "Play" button to watch the objects interract. In order to make changes again to your world, you have to return to the "Starting Time" frame.

• Supports worlds with creation of random pieces.
• Conservation of momentum
• Arrow keys for fine movement
• Tab selects next object
• Objects may be anchored in place
• Selectable Bounded vs. Infinite universes
• There's a little friction when objects wrap around the screen
• Collisions now work
