arena gmf woes

can anyone figure out why this is goofing up for me? i compile it and robots fall through the arena floor like it isn't there.

also using fb's compiler causes it to do the thing where the arena's a black screen and pressing esc crashes the game

That is caused by the compilers (including Serge's) not fully supporting planes.

The floor loses its collision because that's not the real floor.  I used an object called a "Plane" to make the real arena floor, because planes are perfectly smooth (regular objects can be bumpy sometimes).

I believe Serge's compiler can compile planes.  If not, you'll have to edit the compiled file with Notepad++ or something.  Sounds daunting but it's pretty easy.

In hex mode, find the part that says  Plane01 at the end of the gmf file.  Soon after the third and last occurrence of Plane01 there is a four digit sequence that goes

33 33 f3 bf

Immediately after this is a whole bunch of 00's.  Change the FIFTH 00 to a 01, so it should look like this when you're done.

33 33 f3 bf 00 00 00 00 01

Save the file and the Plane object should now work.

Edit:  OH YEAH and the object Plane01 in the RBCollection should look like this

Code: [Select]

*GMID_HAVOK_RIGIDBODY
{
*NODE_NAME Plane01
*MASS 0
*ELASTICITY 0.3
*FRICTION 0.7
*OPTIMIZATION_LEVEL 0.5
*UNYIELDING 0
*SIMULATION_GEOMETRY 2
*GEOMETRY_PROXY_NAME (null)
*USE_DISPLAY_PROXY 0
*DISABLE_COLLISIONS 0
*INACTIVE 0
*DISPLAY_PROXY_NAME (null)
*NODE_TM
{
*NODE_NAME Plane01
*TM_ROW0 1 0 0
*TM_ROW1 0 1 0
*TM_ROW2 0 0 1
*TM_ROW3 0 -1.9 0
}
[color=red]*HAVOK_GEO_TYPE Plane[/color]
*NUMBER_OF_CHILDREN 0
}

FYI: this is also how I made the Infinity Arena.  Planes are perfectly smooth, limitless surfaces with no real vertexes or faces.

that would do it. thanks trov!
