I still can't figure out why my BG object can't become polygonal in collision ("Set object colision to polygons,id")

It always turn out to be box, even "Set object colision to spheres,id".

I use 3dsmax for making this object. Why is this problem???

The inbuilt polygon collision in DBPro is built for simplicity and speed, but personally I find it so simple the constraints make it complicated.

There are various solutions to polygonal collision, here's what I use: http://www.liquid-hosting.com/banshee/pResourceInfo.htm.

There is also a dll by Nuclear Glory, although i've not tried it myself so I cannot advise on it.

note: if you scale youre object in DBP the collision fails

If the object is scaled BEFORE calling the CollisionTypePRO() command for the object, then scaling works.

Intersect Object.

Everything you ever wanted from a collision detection system except understood.

I don't want any includes, Dlls, or something, I just want a simple "Set object collision to polygons,id".
This command still worked at DBC but in DBPro, problems came...
Oh, yeah... I haven't scaled my model, if you'll ask.

Any ideas of this problem???

No... What I meant to say is that instead of polygons are the collisions, it became box, as if I entered "Set object collision to box,id", But I entered there "Set object collision to polygons,id".

ive not tried it but nuclearglory's dll is the only way to go if you want decent collision....either half the board has joined together and lied about how good it is, or its a damn good piece of coding.

ZEDWARE website coming soon... //END TRANSMISSION//

I'm having the exact same problem here when I use the
"Set object collision to polygons,id" command it just doesn't seem to work. How does this come?? About the scaling, yes I tried putting the scale command above, didn't work. I also didn't scale at all but it still didn't work. What am I doing wrong??

@Soundbox
You were using our DLL with the scaling command right?

I don't know if scaling affects the "Set object collision to polygons,id" or not.

When using our system, it is important to put the block of constants at the top of the program. Otherwise everything will get pushed through as 0 and make trouble.

Make sure to examine our download, as it does work well.

One problem you could be having with our DLL, is if you're using a loaded .3ds model, as the triangle data seems to be corrupted in the memory block so our DLL receives a bunch of garbage data. If this is the case, try converting it to an X model and give it a run.

EDIT:
@M00NSHiNE
I do know that you were looking forward to a version of our DLL that handled corners better without jittering around.

We have released v2.01 (in case you didn't know) and it does have a lot better handling of corners without jumping around.

Just want to make sure you knew we had a new version out

No I haven't used your dll. I was just wondering why the normal darkbasic pro command for polygon collision doesn't work?
But there seems to be no other option than to use your dll, I only find it a bit weird that darkbasic hasn't a proper command for this.

well, even if it would work...DBP's standart collision system is slooooooooooooooooow so why don't you try kensupen's .X collision code or nuclearglory's .DLL

If you really really really want to be use rudimentarry collision then you can use set object collision to polygon. You will not get the results that you are after as one check object HAS To be cuboid, only the object you are checking against can by polygonal.

The reason it has taken this long to get to this answer is because we really are trying to help you by saying there are much simpler & faster methods of collision than the very generic method included.

Also included is the command intersect object, this will give you all the power you need to do ANY collision task in DBPro. My download based upon Kensupens research help to teach some of what you can do with this command to you, if you dont like the #include command because your allergic to the hash key, then just use it to learn from.

Failing that use the .dll from Nuclear Glory, it is widely supported here and very popular. It is also simpler to use than the inbuilt collision system, faster and from what I gather more accurate.

I tried to use nuclearglorys very promising code. 2.01 demover.
However, it seems that i cant rotate objects that I want to make Polymesh detection on, it seems that the DLL remembers the initial position of the object and work as if it still was in that position when colliding. Any suggestions ? Any way to reset and start from the new position? (Ultimate Performance is not needed, rather excellent collision detection)

It surely looks promising, and i'll be the first one who buys it if they get the rotation to work properly. I have a project that is depending on this solution.

Greetings,

Yes, it wasn't coded to handle rotation/scaling yet (only movement)

I have made notes to put in rotation/scaling support for the release.

Thanks for the post

Greetings,

Version 2.01 does not have rotation/scaling support. I will add that in the upgrade for v2.02. (All buyers get free upgrades, for anyone who doesn't know)

@LamptonWorm
Thanks a million. I'm glad we could help

As you may already know, we have placed testimonials on our website to assist in the promotion of the DLL. Would you be so kind as to let us use your last post as a testimonial on our website? No obligation. And if you're okay with that, is there a name you would like placed next to the testimonial?

Again, thanks a lot
