RPG Sprite problem...Help!!

01-25-2002, 10:16 PM
Im trying to create an RPG based on the Rosebud Thriteen Code. Ive got the graphics improved and got the character on the map sprite properly working. Ive figured out how to do everything for the RPG now except for one hitch. On the battle screen, i use a map/tileset screen to create random ground each time the battle screen is called. On top of this i place the main character sprite(animated) and use the rosebuds code to load an enemy and place an enemy sprite(animated) on the map/tileset ground. The problem is that the enemy sprite appears wrong. about the a quater of the top half of the sprite appears correct and and the rest looks strange without all the colours. Im using the same code for the enemy sprite as the Main character sprite, but with different picture boxes. This is the first time ive used sprites as im a beginner and would love some help here :(

Here is the code:

it could be that your picture box isnt big enough and it is causing some clipping problems, or something like that.

01-26-2002, 02:01 AM
Nah its not that Kitaiko. i have tried that before. The pic holders for the enemy and main character are the same, same as the masks. ive checked it completely. Also if i put the enemy pics im using thru the char holder and mask, the enemy pic comes out fine so theres a prob in the coding. Im guessing that theres a buffer getting full??? As im totally new to sprites i cant be sure.
im guessing that the problem is in the BitBlt or getpixel or setpixel.
Any help would be appreciated...

I saw somewhere about a vbSrcErase or something, that can be used where u put vbSrcPaint for example. Should i be using this anyone?

Well, first off, let me say I'm honored you would base your game off the way mine works. I've got it now so that the Main Character is masked when he is walking around on the World Map. You can easily take that tid bit of code and apply it to a battle
I wish you luck in your game, and hope to see a copy

By The way, post your game, and I'll take a look at it, I might know the problem

(You see, this game is based on a story that I've been writing for the past year, and though I can't fit all of the Characters into the game, I have the main character, and the name out, and since the person who downloaded this is in the UK, I'm so happy that This game is on Other Continents, too, I really am.)

Heh well i got almost everything worked out except that enemy sprite glitch....(Spent a lot of time D/L ing other games and tutorials off planet source code so i think ill have it solved soon).

And Sure ill post it here when its done. The only thing thats been making me rack my brains lately is sound. Everywhere i find the same bits of code to do it and i cant get sound (WAV/MIDI) to work on my projects. Downloaded examples work in thier original projects but if i copy the code into a new project it wont work!!!

Perhaps ill figure it out from those games ive downloaded....

If im still stuck with this RPG...ill post the game code in a few days as u suggested.:)

Please please please use the tags when postin source code, especially large amounts of source code, it makes it much easier to read because it preserves the monospacing of VB and also the indenting. Without it, many people wont bother to read large blocks of code because they are too messy.

Just a tip :cool:

Whilst on code posting tips:

Use one the various code colorers available from people like VolteFace to make your text look all nice and pretty...... :)

Good News i figured out my problem!! Would u believe all it was, was that i put one entry of "picMasks" instead of "picMask".
This made the code try to use the same mask picturebox.

Doh silly me.

Now the only prob i have is sound. I copied all my RPG files into a project that i downloaded from the Net that had sound and i can use sound. But if i start a new project and try to use sound in my programs it wont play. Is there a component or reference or tickbox in an option im supposed to use, Anyone???
