`Basic collision demo

`This command makes a matrix for us. We use this so we can get an idea of depth in our world.

make matrix 1,1000,1000,10,10

`make our two objects, object 1 will be our character, and object 2 will

`be used for collision

make object cube 1,4

make object cube 2,4

`Now we set up the collision for the objects.

set object collision on 1 `Sets the collision on

set object collision on 2

`Since we're using cube's, we want box collision. This builds a box

`around the objects that will detect collision with other objects with collisoin.

set object collision to boxes 1

set object collision to boxes 2

`We next position our objects apart. We'll leave object 1 at its current spot now.

position object 2,0,0,10

do `initilize our loop

`We only need to follow the z position, because the object only moves

`back and forth in this demo. Feel free to apply other variables if you'd like.

z1#=object position z(1)

set camera to follow 0,0,z1#,90,10,5,1,1

`Move our object when the up key is pressed.

if upkey()=1 then move object 1,0.2

`Move our object when the down key is pressed.

if downkey()=1 then move object 1,-0.2

`We now use the 'object collision' command so we can tell the compiler what

`to do when the objects collide. In this case, we tell the object to move forward

`the same speed the other object moves. If you wanted, you could rotate the object

`to give it the effect it was rolling. Physics can also be applied, such as acceleration

`and decelleration of the objects. For now, we'll just keep things simple.

if object collision(1,2)=1

move object 2,0.2

endif

loop `loop back to the do statement
