Tutorial 5

In this tutorial with have learnt how to use the reactor tool. This is a very useful tool which allows me to mimic the effect of gravity and collisions between different objects. It would be useful to use this tool for an animation of a bowling ball crashing into some pins. To simulate this animation all you have to do is follow the following steps.

First you have to create a plane which will be the ground on which the bowling ball will run down. You have to have the plane at an angle to allow the ball to roll down it. You then have to create the pins and the bowling ball. The next step is to add the ball and the pins to the "rigid body collection". This can be found in the "reactor" menu and then scroll down to "create object" and then scroll across to "Rigid Body Collection". A menu will then appear at the right hand of the screen. The next step is to add your objects to this menu. To do this you have to first click anywhere on the screen to add the "rigid body" symbol and then click on "add". A menu will now appear and you have to click on "select all" and then add. This applies all of your objects on the stage to the "rigid body collection".

The next step is to create a mass weight for your objects. To do this all you have to do is to go the "reactor menu" and then scroll down to the "open property menu". You then have to apply a mass to the mass box for each of the objects apart from the plane which acts as the ground.

All you have to do is now test your animation by going to the "reactor" menu and then scrolling down to "preview animation".
