I am having trouble figuring out how to load a sound (wav) file using the load sound command. I am running DBP from C: and have my .wav file in a directory d:\sounds\. I have typed the command line as load sound d:\sounds\td.wav, musicsnd however when I run the program I get the error message "parameter for load sound do not match 'Filename,Sound Number' at line 8.

Thanks in advance for the help.

The extension for the sound needs to be in quotes

load sound "d:\sounds\td.wav", musicsnd

Hmmm... The line of code should look like this...

Load Sound "D:\sounds\td.wav",1

...make sure your filename and path are correct...

well... Hope I helped...

Programming isn’t an addiction, its more of a mental and social dependancy.

don't hard code your paths, copy the media to the same dir where your exe is and use

load sound "td.wav",1

or make a media sub folder in your game dir and use

load sound "\media\td.wav",1

If you hard code your paths to a root drive/folder and then at some point want to redistribute your game you will be in a world of hurt.
Just some friendly advice

This can be done...

load sound "d:\sounds\td.wav",musicsnd

...as long as this is done first...

musicsnd=1

...but CattleRustler is correct, put your media in your games folder.

Thanks for all of the help, that helped me to solve the problem and then some.

My next problem is that I would like to take a section of a large image, such as a jpg picture and create a sprite out of part of it. I've tried using the command "GET IMAGE" after loading an image with "LOAD IMAGE" however I can't seem to copy a part of the image, what values are to be used in the GET IMAGE command, are they pixel values or something else? Thanks again.

I don't think you can with jpgs but I could be wrong. Have you tried with a bitmap instead, just as a test?

I tried with a .bmp image as well but wasn't having any success. Is it just easier (and usually recommended) to get an image editing program like Photoshop to edit the image? Thanks.

hmm...
this may be one of those cases when DBP is different from my DBC, but I used "load bitmap file" and "get image x, y, x1, y1" quite successfully.

Are you sure you have the same focus? (current bitmap) for both?

Any truly great code should be indisguishable from magic.

Yes, I'm pretty sure that I was working with the same image. What is the parameter range for x,y,x1,y1? Are x,y,etc. pixel coordinates or something else? I would like to try this again.

They start at the top left at 0,0 and go to the bottom right at whatever the pixel width,height of screen is. I think. You have to have the picture on screen to grab part of it using get image like this.


And this will save it to a file if need be.

Thanks for the help and the code. That was my problem, I hadn't pasted the image on the screen first before trying to capture a portion of it. I am trying to create a slot machine type program and I guess the best way to create the image of each of the rotating wheels is to make an animated sprite? One other question, is screen burn a concern when working on games that have a fixed image (ie a slot machine image)? If so, what temporary colours are best to use? Thanks again everyone for all of the help.

I think an animated sprite would do fine. As far as screen burn in ... I don't think that will be a problem unless you leave the 1 image on there for a very very long time. We have monitors at work that stay on the same image most of the time and it takes about 2 years before it actually burns to the screen with todays high refresh rate monitors. And thats displaying the same image (most of the screen as only the small numbers at the bottom change) for about 19 hours a day. Though this may depend on the monitor specs. Take into account also that these monitors clear the screen every frame before drawing the changes (which you will have to do any way or use sync on and let it do it for you) so this may be helping it.

no worries. I don't blame you for not wanting to see other code - it kinda defeats the fun and the purpose. I was offerring before my brain thought it thru. Well, just know the offer always stands (on this and anything else) but will not again be spoken

Sorry to have put you on the spot
