3D Engine?

[dragonguy]

Maybe you are right but the only reason why I created this thread is because I want to learn 3Dimensional Maths and so far nobody has posted a formula that works yet, there have been several good ones but none of them 100% successful, if anybody has a formula that might work, please give it to me and i'll test it.

All my game will be is a 2D game with good 3D maths.

[neat_Kliker2]

just change them till they do work, I had to do that with the custom scrollbars and it isn't 100% but it works good enough.

[dragonguy]

What type of changes exactly should I make? I noticed in the engine I was given by that smart guy- what's his name? positioning objects only involves it's X position which sujests a static camera, I just don't know where to begin changing it.

I'm not askin anybody to make my game for me, i'm just asking for a mathematical equation(s) to make my game possible.

You will find most of your needed equations in the following books (all of them below I've read them and there are good, so I strongly recommend you to buy the books if you're going the 3D route):

Real-Time Collision Detection

The Real-Time collision detection book has alot of valuable collection of detection algorithm for 3D environment. I found it was very useful book and had almost everything needed in 3D.

Remember, even with all the books you've above, you will still need to come up with an equation on your own to suit your game or particular scenario. The good thing is that it will be alot easier and faster to come up with one once you know the drills.

Well a raycaster 3D engine (what Wolfenstein 3D used) is very possible and can be fast too. (I know my raycaster is extremely slow, but I never got around optimizing it)
The speed WILL be limited by MMF2 though. You can do all sorts of tricks to make it faster but it can be kinda hard.

Dragonguy: Yes you should always put a limit on how big you scale your actives. If you scale an object to million times bigger then it will certainly use up all your RAM and swap space and freeze your computer. Easy way is to limit the scale to around 10.

[dragonguy]

I already put in a cap for scale, it took me long to figure out I needed it but I got one in eventually.
Iv'e looked through those books and they all seemed good, they are about calculations i do not need for this game if I was making a game with an irrlicht engine or quake engine i'd definitely buy one of those books.

The calculations I need are rather simple, yet they are completely non-obvious.

The calculations I need are rather simple, yet they are completely non-obvious.

This is what sorts out the real mathematicians from the rest

Making things seem simple is the gift of the genius.

What the !??!

I was trying to use my 3D formulas from a few pages ago to see what result I could get, and I've got a bug where I'm modifying an alterable value and it starts destroying objects.

I only have one "destroy" action, and that's in "start of frame", so it's not me doing it. Adding a never to line 7 stops the objects being destroyed but ruins the 3D effect.

See: (b247)
http://www.dynamicarcade.co.uk/examples/MMF2/3D_bugged.zip

Does it happen for anyone else?

EDIT: It's still doing it in b248b3 and the HWA beta.

[Looki]

Yes, I can confirm this weird bug, using 249 beta.
You can clearly see the object count number decreasing fastly in the debugger.
