3D: Controlling action
Resolving collisions
When a collision is detected, you decide what the result of the collision will be. Different situations require different
solutions. Here are some examples.
An avatar controlled by the user will simply be prevented from passing through a solid object. You may want to
deflect the movement of the avatar so that it moves along the obstacle. See “Sliding along a wall” on page 237 for
more details.
An avatar that moves over a terrain needs to remain at the surface of the terrain at each step. See “Hugging Terrain”
on page 238 for more details.
A ball that collides with a wall will rebound and start traveling in a new direction. The impact with the wall may
reduce its speed. See “Bouncing off a wall” on page 291 for more details.
A ball that encounters a sloping surface may roll down the surface. See “Terrains” on page 319 for more details.
Collision modifier
When you attach the collision modifier to models, it will generate an event when the relative movement of two models
may result in a collision. It gives you the option of stopping the movement of the models at the point near where the
collision would occur.
To test the collision modifier, download and launch the movie Collide.dir.
Set the collision modifier properties and drag the models around. An asterisk appears when a collision is detected.
Collide.dir allows you to set the properties of the collision modifier and visualize collision data.
Adding the collision modifier to a model
The following command adds the #collision modifier to model 2, named “HighImpact”, of the member “3D”:
