Sorry about asking 3 questions in one post, but I figured you guys would like it more than me posting 3 different threads. First question, is there a command like rnd() that returns a float? Say if you put rndfloat(1) you could get .4, or something? I have a shotgun in my game that fires 8 bullets from the shell, and I have a random number to rotate them so they don't all go straight, but it just looks like a square because it only gets whole numbers. Also, I ran into an issue with sparkys collision. When I added TBM, and I got alot of fps, you can walk through the invisible boundaries of the level. You can still walk on the level, but you can leave it. It doesn't do that on lower fps, is sparky's not accurate enough at low fps? I'm using version 1 of it by the way. This is probably fixed in version 2, but you need direct x 9.0c to run it (if I remember right) and I'm using an older dbpro version so you don't need to install 9.0c. Last question, whats the best way to design levels for games? I'm not looking for anything specific, just wondering how you guys do it. Sorry if these questions are confusing Thanks in advance

answer #1: I don't think so, I just usually do this: (rnd(10)/10.0)=random float 0.0 to 1.0

answer #2:
Quote: "When I added TBM, and I got alot of fps, you can walk through the invisible boundaries of the level. You can still walk on the level, but you can leave it. It doesn't do that on lower fps, is sparky's not accurate enough at low fps? "

maybe the camera is going so fast that the collision entirely skips over the invisible wall?

answer #3:I think the best way is to either use or create a level editor that does what you want and can export a script with level data and a dbo of the static level scenery, and then write a parsing system that loads the script so that you don't have to put any of it into code, and you can modify levels without recompiling.

1- Why not just do something like:


2- Why aren't you using DX 9.0c? I wouldn't expect very much to work well if you are using old versions of software (and DirectX). I use sparky's (current) all the time and have never encountered this precise error.

3- Level design is a big subject. There are a lot of threads regarding level design in other areas of the forums, try here:
http://forum.thegamecreators.com/?m=forum_read&i=19

Level design could mean any one of a large number of different elements of game design from concept through to modelling or even gameplay, which part do you mean?

I'm happy to help where I can please don't think I'm being pedantic!

EDIT: Beat me to it TheNerd!

If I remember right I read somewhere that multiplication is a whole lot faster than division in DBPro (like 35%)... that being said it would be beneficial to just multiply by ".1"

If at first you dont succeed, LOWER YOUR STANDARDS.

A random float function with precision:

@thenerd My bad, I worded the 2nd question wrong I meant that when I added TBM, the camera moves in really small steps, and maybe sparky's can't detect that (at least v1 can't, which I'm using because v2 needs direct x 9.0c, which brings me to...)
@baxlash I'm not using 9.0c so people don't have to install it when they play it. I also do it so I can play games I make during school while I'm supposed to work They don't have 9.0c on them. Installing 9.0c is hard without admin privileges (if not impossible) and the computer admins are already watching me since I put Halo PC on the schools network drive. My bad, I meant how to model/texture/lightmap the level. I don't think you're being pedantic, mostly because I don't know what that word means
@sneaky smith12 Really? I'll remember that.
@Sasuke Thanks for making the function, I'm sort of lazy myself...

Thanks for the responses.

Darkbasic can't run without DirectX 9.0c. End of?

Well, yes and no. You can run a DBPro game without it, but only if it was compiled in an older DBPro version. I mean REALLY old (I compile with v 1.057, the current one is v 7.4, isn't it?). You do miss some things by doing this, like the .dbo format and newer commmands, but I heard holes can appear in converted models in .dbo, and I never used them anyway. DBPro plugins will still work, but I'm not sure where you would get the older version of DBPro, my brother had it lying around. So, yeah.

@baxslash and Kryogenik... take a look here:
http://forum.thegamecreators.com/?m=forum_view&t=23118&b=1

Multiplication is quicker for whatever reason it may be, but the noticeable difference is when you have the divisions ran over and over in a loop.

If at first you dont succeed, LOWER YOUR STANDARDS.
