Now that you see how easy it is to make an object and put it into your level let's learn about some of the properties available to us to make things interesting.  Properties exist in the .gam file on the object page we set up in the previous section.  From that page we determine how the object behaves, if it's destroyable, set the point value for destroying it.  But first a boring but helpful setting....SIZE.  Here's a shot of our ball in D3Edit.  It looks tiny next to a player but it's really 30 units in diameter; much larger than a player.  To make it proportionate to it's actual size, set the 'SIZE' entry to the object's radius (not diameter).  The 'After' shot is from D3Edit after I changed the size  from 2 to 15.  Since you can't see the object in 'Texture View' (without hacking the D3.hog) this is the best way to help place the object.  If you really have to be specific on the placement you'll have to know it's exact size and calculate were to insert it

Before:

After:

I'm just going to address the settings I've marked or this would turn into a ten page essay.

1) Score:  Pretty obvious.... set it to 500.  This will be the score for destroying it.  Remember to set a value, DBL-Click on it or
mark it the go to EDIT-MODIFY SPACE.

2) Bounce:  Get to it by expanding the PHYSICS CHUNK  branch then the FLAGS branch inside PHYSICS CHUNK.
If you tried our object at the end of our last tutorial you may have notices that when it hit a wall it just kind of slid along it.
Turn on 'Bounce' by checking (or X'ing) the box and it will bounce of walls and other objects.

3) Fixed Rot Velocity:  Meaning rotation velocity.  We are going to have our object spinning.  By checking this box it's speed
won't be affected by hitting it.  If we don't set this, impact from a weapon, object or colliding with a wall can speed up, slow down,
or stop the rotation.  Check this on.

4) Lock X, Lock Y.  Locks the object from moving on that plane with hit.  To keep it from moving at all, Lock X,Y,Z.

5) Number of Bounces:  VERY DANGEROUS!  Make sure it's on -1.  I experimented with this.  When I set it on 3 bounces
it would bounce of a wall up to 3 times.  On the 4th it just past through the wall and out of the room instead of bouncing of it.

6) Initial Rotation Velocity:  Choose the axis or axises you want it to rotate upon.  I'm going to set y = 1500.00.
You need to use a high number.

7) Size: Discussed earlier.

8) Hit Points:  Amount of hit points required to destroy it.

9) Uses Physics:  Uses the specifications of the Physics Chunk (rotation, velocity, etc.)

10) Destroyable:  Must be check if you want it to be destroyed.

Now for some quick scripting.  Be default an object with an initial rotation velocity will spin unless told not to. Let's start with the object NOT rotating.  Get the  "Set movement type .." action as shown to the right.  Set it to none as shown below.  The name of my custom objects balgun1.

When we enter the level it won't be moving.  We'll write a script that starts it turning when hit by a Player Weapon.  We''ll also have it fire a laser when hit.  OWNER is your custom object. For the condition go to Insert New Condition-Binary Statement- Object- (IT is a player weapon) is True. All objects can shot or spew from their 'zero' point.  You do this by specifying GunNum: -1.  In the next tutorial I'll show you how to add gunpoints.  At WeaponName spell out the weapon.  You don't get a list to choose from. Add another action:  'Set movement type..." (same as at Level Start) and set Movement Type to "Physic"

You can also script clutter objects for basic movements along an axis.  With some imagination you can add some life, tricks and traps to your  level.
I'll try to get the GunPoint tutorial up in the next week.

Good luck
