could sombody please tell me what the return expreions for the follwoung commands please:

scale object texture
texture object
scale object (note object size x does not count as the return for this command)

We have make object sphere cube box cone cylinder plain triangle.
but... not return values for the types of objects.

its not meant to return values
scale object makess the textureon the object bigger or smaller
texture object tectures the object
and scale object makes the object bigger or smaller.

Sure. There aren't any.
They set values, not return them.
Same for object creation. What exactly do you want to return?

Do you mean you want a command to return the type an object is?

If not, I have no clue why you would ask such a question

And surely if you've created it, you would already know its type.

i want to know the number of the texture the object has been textured with
i want to know the object type e.g. shpere cube box sylinder
i want to know what the textures on the object were scaled to.

sort of

string$ = object type(object number)
integer = object texture(object number)
real = object texture scale x(obejct number)
real = object texture scale y(object number)
real = object scale x (object number)
real = object scale y (object number)
real = object scale z (object number)

thx

Keep track of it then? None of those things can happen unless you issue a command to make them happen. When you do that, log it somewhere (an array perhaps). You ought to know what state your objects are in, this is just good coding practise.

well yeah the way i usually keep track is by using return value expressions tht come with dark basic.

if i set a size for an object i can return it.
therefor
if i set a texture for an object i can return it. (but i cant)
it makes sense.

thats all!
just wondered!
question answered-do it yourself
shezzz

@TCA
soz just noticed your post

yeah.... i, me, the programmer knows, but (this is not the but lets say)

i did.
for t=1 to 10
x=rnd (2)
if x=0 then make object sphere...
if x=1 then make object box....
if x=2 then make object cube...
next t

now, solve this one
you have 10 objects
print on the screen what type they are.

or even better example

playing a game.
if the camera collides with a sphere then die
if the camera collides with a box then point increase.

(dont be smart and say just make all the phere objects from 1-5 and boxes from 5-10 and check the object number) cus thats obvious and not funny

But logical and pratical - I try to put as much information as possible into the object number (unfortunately its slightly limited as you cant use the full 32-bit range), so for example :

Bits 0-12 - Object Number
Bits 13-15 - Object Type

That way you can get the object number and type in one go without having to resort to other means.

Programming is never funny...

All the more reason for some Object Oriented concepts in dbpro!
Like Object Collections could be used in the debate above

Dim objSphere as new Sphere
for each objSphere in me.spheres
debug.writeline(objSphere.xpos.tostring)
debug.writeline(objSphere.name)
next

you get the idea
just a thought

Wouldnt that get rid of the whole concept of BASIC? Yes, I know VB is OO, but is that really a BASIC?

I would be unstoppable if I could just get started...

Too late now and would be too hard to add. OOP is probably a real pain to design & program. Besides OOP generally adds a small (but still there notheless) overhead for the program. Besides, for the above example OOP would be an overkill.

Terrabyte, objects don't work like that. When you create a box object, DarkBASIC doesn't think of it as a box, it just things of it as a series of connected points (verticies) with textures etc. applied.

OBJECT TEXTURE() would make sense though.

im aware of that rob but i wud have wondered wether maybe dark basic would perhaps store the fact that you started off creating it as an object in memory. and that maybe in one of the later patches they would release a few more commands...i dunno.i was just asking.

@Terrabyte

In which case you could simply store the type when creating the object.

The focus at the moment is on nodetrees and portals, which are basically technologies to speed up your game.

I thought of this also. It would be handy in situations where your using somebody elses 'load world' function for example and you wish to interface better with the objects loaded. So rather than wedge your code into somebody elses code, you could just poll the objects for it's creation type, it'd be trivial for lee to add a creation type in the object structure.

yeah i heard about them.... how much will they be able to speed up a game .. on average... are we talking a couple of frames. or are we talking 10' or even 100's

So what does it return if the object mesh is modified? Technically it's no longer a sphere.

Same for object textures.. it'd only work on primitives. Load in a model and it could have any number of textures applied to it, none of which have been "loaded" so the command would return nothing useful is the majority of cases.

Besides, U6 has the commands to interrogate objects from which you could count indicies, vertices, etc and determine it from that if you really wanted to.

Generally, learning to keep your objects in ranges will help a lot with more complex programming later on.

Any chance of allowing the full 32-bit range for objects numbers too !?

If you were to all email him useless questions and requests for commmands that you're too lazy to build functions for - then sure, he'd have a tough time of it.

TCA's request made sense though and was worth bringing to Lee's attention.

"hte mesh is changed"
yes but it was still originaly created as a sphere and this infomation was stored at the start and i did say how the object starts off as.
anyway it doesnt matter. i managed to do a routine using arrays...

no another topic... Rich You have blocked me on MSN. what did i ever do to you.

All I'm doing so say is:

Dim ObjectType$(NumOfObjects) as string

and:

Make object cube 1,10
ObjectType$(1) = "Cube"

My gran has the mobility of a rusted taiwaneese wheel barrow, and if she'd get off her arse to do that one.

sigh, so your saying it's too difficult to set/clear an offset in the object structure ?. I'd say not. When an objects mesh is man handled the type is simply set to custom or mesh type.

Quote: "

"


While you can do that now with memblocks, it's awfully inefficient solution to a byte/word in the structure..

For a measly 7 primitives it's far from vital. As I said object interrogation is present in U6 and doesn't require messing with memblocks to achieve.

No, unless the lower object commands have an object type it really doesn't solve this problem. Spheres etc have variable detail settings so you can't assume a face count of X is a indeed a sphere.

While I never said it was vital. The thing that has always been lacking from pro, is indeed the little things.
