Can\\\'t find this in any know bugs but scaling and collision don\\\'t like each other

I have a terrain I made ( not using a matrix - .x file ) and when I scale it to the size I want the collision doesn\\\'t scale with it!?!?! So I\\\'m using Fulcrum Physics for my collision detection and that works fine except I cant find out if one object collides with another if you know what I mean e.g.



And fulcrum physics doesn\\\'t seem to have a check collision command!

Thanks, Malb

I've been using fulcrum too and matty's already aware of the contact report stuff. Should he fixed soon - see his thread about updates.

After scaling, I reset the dimensions of the physics objects accordinly and all works fine in that regard.

Hoever, the gdk headers are missing a couple protoype declarations that you will need to define yourself:



Where the second parameter is 0 for normal size values and 1 to get scaled size values.

Hope this helps,

what what? lol

Do those commands set the collision scaling to the same scaling as the object? and what was that about changing headers? or do you mean add the ones you just gave me and call them with 1 as the second parameter and the scaling will work?

I'm a confused little man

Thanks, Malb

I add them to a gdk_missing.h and include that file with #include.

Those commands will return the objects size after scaling - when you pass a 1 as the second parameter.

As for physics, I call myPhysics.setcontrollerdimension (I believe its called since most of my objects are controllers) passing in the values returned from those commands - passing a 1 as the second parameter.

Are you scaling the terrain after you make the collision actor?
If so, scale and then make.
Also, DGDK 7.4 has the dbObjectSize(1, 1) command although you should not need it for your purposes.
I have done contact reports, I am just in the process of documenting and creating examples which is also how I test it.

It seems to work fine now and I was scaling it before adding the collision, I just added the prototypes in and called them after scaling and all goes well
