| Post subject: | RGB stuff? |
Alright i was thinking about a few things (namely the way we did clothing/hair in phoenix), and it got me wondering... is there a way that you can just save 1 STYLE of something, for instance, make a base "shirt" that's solid white, then just manipulate the RGB colors for it, then use it, without making 1500+ individual shirts with different colors? And would it be practical, or would it be something that had to constantly be redrawn? I just thought it'd be a much "better" paperdoll if you could just add a base of different things and go from there. |

People were actually doing this (namely Chase) with the vbGORE engine. 
It is going to require some sort of lighting to have any decent speed. TXC by Aaron (http://www.baronsoft.com) did something like this in DirectDraw I believe. If you want to do it this way, it'd be best to store a buffer for each user what their sprite is so you don't have to recalculate the coloring every time. |

that's what i was thinking. when they equip armor for example, store the value in a buffer, and draw it once, then when it changes, change the buffer. what do you mean it will require lighting? i'd actually checked out ORE a while back... but i never got too into it, the community was quite dead and there was no real support for it. i'll check into it though to see what they did. |

By lighting, I mean hardware accelerated lighting. Its not required, but really going to take a while to draw the image without any 3D effects as far as I can tell. But yeah, you have the buffering idea right - that is definitely the way you want to go. Just a little nit-picking, its not on ORE, but TXC, which was made before ORE.

Obsidian, it sounds to me that its not worth the coding. It's much faster just to color the items different. |

Yes, but faster is not always the best option. If you're going to do something, do it right. |

Coloring the items individually allows you to use a better variety of colors, but is going to cost you a lot more RAM (unless you change MS's code from leaving everything in memory) and you wont be able to make that many graphics on your own. |

Hmm why dont you look at verrigans pixel mod program. that changed colour for another colour. Dont know if its the fastest way. |

yeah i think what i'm going to do, is make a certain RGB, like 200,200,200 able to be changed for armor or weapons or clothing or whatever (which actually is a bad way of doing it now that i think about it... i'm going to have to put some more thought into this). At any rate, it should probably just reuse part of those loops i saved using Red's tutorial. thanks for the info guys. |

From a DD surface, you can get a byte array, pass it to a function ByRef, and modify it. If you make the function that modifies it in a C++ DLL, it will still be pretty fast. Byte manipulation in C++ is pretty basic, and with a little primer you could find your way through it. There are pretty much three options to using DD and modifing the screen like that. 1) Do it with code in VB (Slow) 2) Do it in DX3D (Fastest) 3) Do it in a C++ DLL (Probably the best option if you dont want to change to D3D) |
