I got a problem

When I compile any of the demos I get this error:

Command in DLL command-table duplicated (NDB.dll:NDB_DestroyVehicle)

then the program runs very wierd or just crashes.

Just Totally Awesome!
This is by far some of the coolest things to happen to DBP.
GREAT work! I love the joint demo, my mind is on over load, thinking of ways to use it.

Awesome, though i am having a couple of probs. The programs run very slow when making new objects, and the message box at the top flickers constantly. Also, the materials demo doesn't work for me. I just get a plain blue screen and can fire balls...

Still, excellent piece of work, and im very excited about starting some vehicle demos

@Flashing Blade
Try updating darkbasic to v5.7, that worked for me. The demos now work fine, however I still the same error message at the beginning everytime.

@ Oliver, I'm on 5.7

Most of the demos compile & run, but they don't look right. The ones that work the text instructions flicker and seem to run at low fps. The FPS demo compiles and runs but is virtualy un-controlable.

Redownload and install.

Make sure you put both the new Newton.dll in the project folder and the new NDB.dll in the plugins folder.

I had 2 entries for NDB_DestroyVehicle in the string table... I've fixed the NDB.dll, and am uploading a fixed version of the wrapper now.

those who have already downloaded can get the fixed NDB.dll by clicking on the download button in this post.

for those having problems
with the new wrapper, you ONLY need NDB.dll in your plugins-user directory. there is no longer any need to Newton.dll to be anywhere on your system, it's built into the wrapper. if you have Newton.dll in your plugins-user directory, or your program directory, delete it! have a look at my demos, none of them use Newton.dll

also, I did all of this with DBPro version 1.055, so I'm not sure if there are any problems with other versions... I was too scared to update to 1.057 mid-project

anyone having problems, please post your Windows version, and what version of DBPro your using!

@ Walaber thanx - d/loading now

@ Chris K - I think the NBD.dll now has Newton.dll built in so I don't think you need newton.dll in project folder.

In under 30 seconds i added rag dolls to the FPS game. All I need now is a vechile (though that will probably another 30s) and I'll have the next halo game done by this evening!

Yippee got it working.
I recently re-instaled DBpro but never updated IDE. Just updated IDE and works fine now.

This is top stuff - well done Walaber.

Neat!

The physics reactions in the vehicle demo need toning down, though. It's nearly uncontrolable.

This works quite well on my machine. However, I have one question. Even if I set the sync rate to 0, the maximum frame rate it hits is 60. I know that my machine can go higher, is it something in the DLL itself that maximizes the sync rate?

I got a problem, the precompiled demos run flawlessly, but when I try to compile my own, they start at 33fps max where as the precompiled demos start at 66fps. Use can see the newton objects being made in my compiled demos, but the precompiled demos you dont. Also the vehicle demo stops as the truck is being created and says file not found

I have also tried the new dll that was posted after the initial release of the wrapper

Im using Windows XP SP1, DBpro version 5.7

Very very nice Walaber . May take me a while to get used to the commands, but I will .

The vehicle seems to be driving on ice though, or it just has super wheel spin or something, cos if you get up to a certain speed, turning just makes the car spin. Any idea how to counteract this effect?

Isn't it? Wasn't it? Marvellous!

I can't get it to work...
The program compiled and everything, but when it starts I just get a black screen and eventually the program quits itself (or I quit it via Control-Alt-Delete). I rem'd the subroutine out of the program, and it compiles and runs as normal. What am I doing wrong??

Here's the initialization routine, for anyone who's interested:

Thanks in advance to anyone who can help!

{PS} I'm running DBP 5.7 under Windows XP SP2. I've tried the code in BlueIDE and TwilightIDE, and it failed both times. The demos compile and run fine.

If I make the torque=315

if keystate(17)
ACCEL = 1
Torque# = 315.0
endif

and steering angle=35

MaxSteeringAngle# = 35.0 - ((vel#/100.0)*35.0)

Then it drives alot slower but the ice driving disappears

I'm having problems compiling the demos, I get 2 illigal ops then nothing happens, I'm just sitting looking at the ide.

Using Win98SE and DBPro 1.055.

I tried upgrading to v1.057 but then nothing compiles at all.

Yer all earlier versions of the wrapper that I have used have worked fine after a couple of illigal ops it's just now it's started with the major problems.

Hopefully this doesn't mean I have to upgrade my perfectly safe Win98 PC to the brightly coloured evil that is XP.

Flashing Blade - glad you got it working!

Oliver - very cool! does shooting the ragdolls work without any modification? i think it should...

Merix - sorry, that's a typo. it's the "docs" folder!

dark coder - seems to be a Win98se problem... the old wrapper had problems for Win98se users too... perhaps I can try recompiling the DLL in Debug mode, and see if that changes anything for you...

Hamish McHaggis - the vehicle demo is VERY simple, and in a real game, you would want to do something other than just set torque to a constant value. I think it's slipping because the tires have too much torque constantly, so they lose traction and spin too fast. There are lots of resources on the net about coding a "gearbox", adding something like that would probably help a lot. at the very least, having the torque ramp up from 0 slowly would also probably help a lot. the suspension settings of the truck also come into play. I have it set really "bouncy" in the demo.

Mr Underhill - couple problems with your code. in general you're missing steps. for example:
Quote: "ndb_player=NDB_NewtonCreateConvexHull(3)
NDB_BodySetDBProData ndb_player,3"

the CreateConvexHull command creates collision geometry. this is just a description of the shape. then you must call NDB_NewtonCreateBody() on that collision to make it into a Rigid Body. after that call the SetDBProData command.

jwurmz, no, a plane is by definition infinite. you need to perform some kind of check on your own, and turn buoyancy on/off based on if the body is in your "water volume" or not.

Yeah, just found that out from reading demo #1. I was probably looking for an object that doesn't exist, hence the hold-up. I'll try again, and I'll report my results. Thanks, man!

walaber: figured so, shouldn't be a problem making zones. another question (hope you don't mind) - is there a way to load a prefab mesh (X mesh), scale it about the x, y, or z axis (each axis allowing for different amounts), and create tree collision from it that takes into account the new xyz scales? i've tried a few things, but i'm stuck...

OK, I'm back from fixing the code...no luck . It still gives me a blank screen and shuts itself off. Here's the troublemaking code:

My problem is that I don't see a problem . It should work fine, right?
Ah, well. I'll just re-make the whole program to make it work. It's not like I had much to begin with , I mean,60+% of the old code was physics to make it work, and Newton pretty much makes that obsolete already.

I am getting two weird issues with the FPS demo but I think it has to do mainly with slope. Sometimes the ability to jump just completely goes away, also I've noticed if you jump you also seem to bob back up a tiny bit after you land. But on certain parts of the level (the terrain is uneaven and hilly so like I said, it might be slope) you can't jump at all.

The second part is similar, sometimes you can't shoot. The bullet isn't placed and nothing you shoot is affected. It seems to turn on and off randomly.

And I still can't get above 60 FPS. Any ideas?

jwurmz - not currently, because when you access the vertex data, DBPro doesn't account for scale. the object is scaled with it's rendered, it's base data doesn't change. however I think I have an idea for a solution that may be in an upcoming release. for now, just pre-scale in your modeller!
