It's impossible to get Text Width/Height from a multiline text box. You specify the width and height by the size of the box.

This plugin is fantastic!
I have been playing with it all day and I am very impressed. One thing that does strike me as odd though is that alpha only uses a range of 0 -100. Is it possible to change it so that it uses a range of 0-255? As it is, it doesn't match the values that a PNG file has and 0-255 would certainly make things easier.

Thanks for listening and THANKS for the plugin

Scraggle,

Thanks for the praise

SilentS has been working on v3.5 which should be available very shortly. This uses alpha ranges from 0-255 and also has all the new batch commands.

Cheers,

It's not impossible.

If you use DT_CALCRECT with the return value from DrawText (which will be the height needed to contain the text) the width will be the width of the box supplied to wrap the text too.

On another note, have you considered "caching" the CALCRECT calls? If you call GetWidth followed by GetHeight on the same string, it forces two calls to DrawText(), when only one is really needed. Since i dont know how DBPro handles the string pointer passed in, you could cache the calls, and the pointer, and if the pointer is the same, just return the cached widht/height. Just a suggestion. If not, there could be explicit calls to do this, so the caller has to be aware that they are getting the cached data (ala, make one call to "size" the string, and one call each to get the height and width).

I am proud to present D3DFunc V3.5.

Sorry it's a bit late, but it's here now.

The biggest addition to this version is the introduction of batching for basic 2D operations, and updating of 3D batching to bring them inline.

Unfortunately with this version there are a few changes that you should be aware of that will break existing code. These includes changes to alpha and some command parameters. All changes are documented, along with additions in the Moving to V3.5 help file, which can be found in the download named D3D_BREAKINGCHANGES.htm or linked from the D3DFunc index after installation.

I intended to write some new examples to go along with this release, but since I haven't done so yet, I didn't want to keep the release any longer. I have attached a small sample I put together to try out 3D dots, it contains the source and a compiled version. In it's current state, it's rendering 75,200 3D dots in about 80 FPS using the new batching functionality.

For this release I added a lot of the new functionality, while porting over the code previously written by Cloggy and myself. Due to this, any problems you come across are my fault, so let me know and I'll see what I can do to fix them.

I'm pretty sure I had other things to mention, but I can't remember, so I'll leave you with the downloads available from the site by Cloggy here.

FANTASTIC!

On the day I discover this plugin, I ask for one thing to be implented and here it is less than 6 hours later fully functional!

I'd like to think it was my influence and kind words that made you rush into action and get this sorted but (reality check) I know you have been working on this for a while and my request was very coincidetnally timed.

I am very impressed with this plugin. Not only by the functionality of it but the professional feel it has to it. It is very rare that a plugin comes with fully integrated help files that make you feel like this is a complete inclusion into the DarkBASIC product.

As for the MAKE TEAPOT command, it is hard to believe that DBP has managed to survive so long without such a command.

My hat goes off to you ... both off you.

Thank you VERY much

@ Scilynt & Cloggy,

Just repeating what Scraggle said - excellent and thanks... to assist the imagination-challenged, could you perhaps some of the potential uses of the 2d and 3d batch commands in games?

a long time dabbler with DBC and DBPro with no actual talent but lots of enthusiasm...

As one of those imagination-challenged I can't really help but say, any time you're using multiple dots, lines, 3D dots or 3D lines, then you're probably better off using the batch commands. It's only an addition two commands, or three in the case of 3D dots, but the improvement in performance greatly overpowers the cons of having to implement two extra commands . Obviously you're not going to get much improvement for 10, 20 or 30 lines, but once you get over 100 the benefits become obvious.

And to Scraggle, 255 alpha was in the last release, but you had to enable it with an extra parameter on D3D_Init, this release just made it standard. Also regarding the teapot command, I know, every test I do now uses teapots rather than cubes. It's like to move from Yahoo! to Google all over again .

Duffer,

I believe morcilla uses this plugin on his excellent Solar System Simulation here http://forum.thegamecreators.com/?m=forum_view&t=68745&b=8

Also, philip has created a black hole code snippet here http://forum.thegamecreators.com/?m=forum_view&t=74036&b=6

EDIT - BTW I intend to compile a version for 5.9 tomorrow on my work PC.

Cheers,

Have you checked the breaking changes document to make sure you're not using any commands that have changed? From memory the ones with command name changes are the 3D text, teapot, and torus object commands. Aswell as the 3D batching functions.

If this is not the problem, could you provide some example code so we can try to identify the problem?

Oneka,

Can you try the following very simple code to see if you still get the problem


That works fine here.

Also what version of DBP have you got and what version of the dll?

There is a U6+ version and a U5.9 version.

I'd just like to mention that the 5.9 version, isn't only for 5.9, it should work for any release after, and removes the need to D3DX9_25.dll, this means that the intended user of your app/game doesn't require the April '05 SDK, or to have installed the DLL seperately.

Do the other commands work? If so, try re-downloading and extracting it again.

If not, make sure you have a file named D3DFunc.dll in your DBP-Root\Compiler\plugins-user\ folder. I know you said it was extracted correctly, but perhaps that file wasn't.

Not sure what the problem could be, the file version should be 3.5.0.0. Though even older versions shouldn't cause a problem.

Do you have two or more directories for Pro? Perhaps one for testing betas, if so then make sure you've got it in the correct directory for the version you want to use.

I'm going to have to head off, it's 02:11 so I'll be needing some sleep. If the problem has been sorted, then I'll resume this tomorrow (technically today).

This is extremely strange. The only way I can get close to the same error is by removing the dll from the plugins-user folder.

With the earlier sample I provided I get this error.



Can you post the error report you get with the source I provided please.

OK...D3D text just got better with U6.

One problem with anti-aliased text was making a text image with a transparent background. You had to make a bitmap with a color key (black, for example). Using one colour for transparency doesn't work for anti-aliased edges, it looks horrendous.

In U6 we can now have transparent bitmaps - SET BITMAP FORMAT 21. Below is a before and after image of the results...

If you look at the words 'Main Menu', in the first image ther is a slight black border which isn't present in the second which makes it look alot better.

Okay thanks for the report, that's because only one font is initialised, and we make no checks to make sure that the font specified has been.

Glad it's now working for you.

Since im not sure if you understood what I meant or not, I figured it would be easier to just implement the function myself. Here it is if you wish to include it in your dll.

After re-reading your message, I can see what you want so I'll add it in, though it will be slightly different than your function.



There's no need to include the height parameter since the calculations don't care about it.

Hey I have a request...its not really that big of a deal but I was wondering if you could set it up so that when using commands like
D3D_COLOR would it be possible if you could set it up so that its just two parameters that are needed?

example D3D_COLOR DWORD,APLHA

so I can do things like D3D_COLOR RGB(255,255,255),255
only so that I can keep some code small....its not a biggie so if you dont I understand just trying to make some things easier xD

Ok, my original post was silly, but I have a question now...

Why is it that when I use D3D_Color to change the colour ( specifically the alpha ), that it doesn't take effect on the 3D lines?

To clarify, the colour changes, but the alpha does not.

[EDIT]
Gleh, never mind, there was an error between the chair and keyboard...

Jess.

Alrighty...

Now, if I have a ghosted and faded object on top of a 3D line/Dot, etc, it will not show through the object.

I understand that the 3D drawing is probably done after the object rendering, so it should be possible to see what's semi-transparent, no?

Jess,

I have done alot of testing on this and have found no way of making the line appear behind ghosted objects. I think that the DBpro objects are being rendered by the sync command whereas the d3d stuff is all done before the sync. I'll have another look but don't hold out much hope.

No worries, I'm happy to put up with it

TBH, I'm only using DBP in this case to prototype a game I want to make on the DS in C++ So, it's not terribly important, I can revert back to old methods

And, here's another one...

If there are ANY objects on-screen that have the 'Set Alpha Mapping On' command applied to them, then the value of the Alpha Map will also effect 3D lines and Dots...

Thanks to the promptings of philip I decided to send copies of the d3dfunc source to Lee along with and example of the 3d line rendering problem. He kindly spent some time last night looking at the problem and concluded that due to the fact that DBP clears the zbuffer before rendering it's objects, this problem will always occur.

He has however suggested that we touch bases after U6 has been finalised and his schedule eases, so we could discuss possible enhancements to DBP to help resolv this problem.

Not sure when this will be, but hopefully we can get it resolved.

EsteemDE,

I have managed to reproduce the problem on my 5.9 machine. I would suggest downloading the version 3.2 at the moment, I will try to resolve the problems and upload a new version later.

EDIT - I've now had a look and I can't even get the 3dtext command to work with a much earlier version of d3dfunc (V2.1) . The only thing I can think of is that I tried upgrading the version of DBPro on this machine from 5.9 to U6B2 but has some problems and reverted back to 5.9. If anyone has 5.9 that hasn't tried upgrading DBPro yet can they give this a try. Otherwise I think I'll have to get round to doing a complete uninstall/Reinstall and try it again.

Cheers,

Cloggy

I still have the text crashing problem. It's when I create a fourth D3D Text, part-way through the program. It doesn't crash for me ever on 2 machines, but it does every time for Rick Vanner.

One of my machines has a Geforce 5200 FX 128 MB card, the other is an ATI mobility Radeon. I don't know what Rick is using.

The code that causes it is quite simple:

d3D_font 4,"Arial",24,0,0,1
d3d_color 50,50,50,255

So I keep missing you on MSN. What version of DBP are you using?

I had some problems with v3.0 with U5.9 but seems ok with 6+

I'm running 6.1. I removed the D3D Font 4, and used a font that already existed in the program elsewhere. This fixed the problem. So Rick's hardware must have an aversion to 3 D3D Fonts (the 4 is misleading, there's only actually 3).

Admiral,

Ir's not a bug, When you change the resolution all the fonts you created with the DirectX dll are lost. You need to call D3D_init and all the font creation routines everytime you change resolutions. It's the same as DBP and Images. They are lost when resoultion changes as well.

Cheers,

Cloggy

Cloggy - Have you thought about including 3D sprites in your DLL? Such a feature would be pretty damned handy for drawing fast particle and billboarding effects, and wouldn't be very hard at all considering the amount of stuff your dll already does.
