I've finally figured out how to get ODE to work correctly with a triangle mesh level! I've attached the example to my post. I've included with it the ODE dll that works for 6.2 and above. The dll has been recompiled to use the latest version of the ODE library. If the example doesn't work, try putting the new ode dll in the plugins-user folder.

You need the latest version of DBPro (6.4) for this to work. You also need to replace the current ode dll that is in the plugins-user folder with the dll included in the zip file. You will need the October 2006 dx runtime or later since I compiled the dll using that version of the sdk.

Enjoy!

I'm testing this now, i always wished the triangle mesh features would work.

[EDIT] It seems you didn't include the functions you use to get player and camera position/rotation. For example, you have 'campx()' in your code but there is no function defined as 'campx()'. Will test once i change all those back.

[EDIT2] It doesn't work for me, i just get an error when i try to run it.

---

It does for me as well.

Windows just gives me notice of an error and terminates it.

---

Oops. I've fixed it now. Just download it from the first post.

---

Works fine for me!

Can you position map.dbo freely or is it always in 0,0,0 ?

---

Works fine here also. I might convert your sample to work on DGDK.NET using the ODE plugin for that as well.... if you don't mind of course?

---

Still crashes for me

---

It does not work for me. I have DBpro ver 6.2.
I've tested the Dll on another project but it does not work. I've tested the code with the old Dll and it does not work.

Any ideas?

---

Apexnow, yes you can convert it. Just put my name in it.

Image All, can you tell me what error message you get?

Trinita, does it crash on compile, or does the collision not work correctly?

Juso, I don't think you can reposition it after you use "ode create static triangle mesh", but you can reposition it before.

---

It crashes on compile.

---

What error do you get?

---

Here's a new version that is in 3rd person instead of first. I've fixed the problem where you slide down a slope. This new version requires sparky's collision dll which can be downloaded here: http://forum.thegamecreators.com/?m=forum_view&t=74762&b=5

---

The exe file (ode.exe) doesnt work, with the new dll and with the old. It simply opens an windows XP error window. I've tried with the new one (i already have sparky) you uploaded, but gave me the same result.

My specs: Windows XP Pro sp2 -- DirectX9.0c -- 1 Gb RAM -- Intel P4 3.00Gb -- RADEON X700 PCIExpress 128 mb -- DBPRO ver 6.2b

[EDIT]: It's working, i dont know how i did it...great!

[2nd EDIT]:It works only in debug mode with old ddl. I must upgrade to 6.4....

---

For those people that can't get it to work. Read the first post again, I've edited it to tell how to get it to work.

---

I still wonder how to reposition the ode object. It always stays in 0,0,0

map.dbo can sure be positioned but then it and ode object are in different places

---

Juso, do you mean before starting the simulation? If so, reposition the object before applying the ode create dynamic triangle mesh or related command.

If you're talking about move the object after or during simulation, the best way is to cancel the ODE mesh object, reposition it and reassign it to the simulation again. Moving objects directly during simulation isn't really a good idea as it b0rks the behaviour up a bit.

@APEXnow
Where exactly should positioning take place in this example (coolgames above) before simulation. There are only six lines, I have tried all! Moving eg map slightly to left 70,0,0 but how? "Position object 1,70,0,0" or "Position object 3,70,0,0" moves map not ode object

load object "mediamap.dbo",3
make mesh from object 1,3
convert mesh to vertexdata 1
make object 1,1,0
exclude object on 1
sc_setupcomplexobject 3,1,4

`triangle mesh...
ode create static triangle mesh 1
ode set contact fdir1 1,20
...

---

You need to position both object 3 and object 1 to the desired position before you call ode create static triangle mesh.

---

No it wont succeed !
I really think its unpossible to position ode triangle mesh elsewhere than in 0,0,0
Can someone solve this problem?

...
load object "mediamap.dbo",3
make mesh from object 1,3
convert mesh to vertexdata 1
make object 1,1,0
exclude object on 1
sc_setupcomplexobject 3,1,4
position object 1,70,0,0 `here you try position ode object
position object 3,70,0,0 `and map... but ode stays in 0,0,0

`triangle mesh...
ode create static triangle mesh 1
ode set contact fdir1 1,20
...

Here only map is moved, ode stays in 0,0,0

---

change this:
+ Code Snippet

position object 3,70,0,0 `and map... but ode stays in 0,0,0

to this:
+ Code Snippet

position object 3,70,0,0 `and map... but ode stays in 0,0,0
fix object pivot 3

this will reset objects pivot so that the new objects position is interpreted as the default NON-modified position.

Then ODE should create collision mesh perfectly.

---

No way
"fix object 3" doesnt change anything, not even
both "fix object pivot 1" and "fix object pivot 3"

More ideas, please!

---

Im convinced the implementation of ODE Physics for the DBP Engine basically blows, theres gotta be something better. Sorry to say.

EDIT: Ok, that was a little harsh, it might be really nice for limited number of certain types of things (uses) but not to stable/capable for more complex things.

---

I've attached a fixed version of the dll. This will allow you to reposition the object before you call "ode create static triangle mesh".

---

Thanks coolgames, but this new dll crashes both in 6.3 and in 6.4

---

It does? It works fine on my computer. Can you give me the error message?

---

I might have dx9 feb 06 or apr 06. Should I need newer?
I will test it more at weekend.

---

You need October 2006 or later.

---

It crashes for me too

right after compile has finished I get a "ode.exe has noticed a problem and needs to be terminated" error message!!!

how can I fix this

---

I've replaced the old dll, have the latest version of dx and dbpro and it still doesn't work

---

Someone c++ guru should take this as a challenge and fix that dll

---

Hello ,I use ode in my games and it works fine with everything !

Just use : -DBpro version 6.1
-This version of the Ode DLL post by IanM (Download)
-This code to load a Triangle Mesh :
+ Code Snippet

Rem create the object for colision :

load mesh "YOUR OBJECT.X",1
make memblock from mesh 1,1 
delete mesh 1
make mesh from memblock 1,1
delete memblock 1
make object 1,1,0
delete mesh 1
ode create static triangle mesh 1
hide object 1

Rem load the visible object :

load object "YOUR OBJECT.X",2

To install DBpro 6.1 you must uninstall Dbpro completely if you have a newer version ( sorry...) and download the update from : http://darkbasicpro.thegamecreators.com/?f=upgrade_6_1

EDIT : You can position object during the game with this version of the DLL by using the command : "ode set object position object,x,y,z"

Good luck !

Nobody wants to try ?
