Why this recent spate of meaningless questions I wonder?...

Anyway, as your question doesn't ask anything precisely, here's one possible answer you might be after:

Objects spin in 3D through 3 axis - X, Y and Z.

Imagine a cube with a hole running through it placed on a vertical flag pole. Spin the cube and it rotates around the Y axis.

Now imagine that cube on the handlebars of a bike. Spin the cube away or towards you and it rotates around the X axis.

Finally, imagine the cube on the lance of a jousting knight on horseback. Spinning the cube left or right rotates around the Z axis.

The complete rotation of an object is 360 degrees, starting at 0 and to rotate it 10 degrees, you simply add 10 to it's current angle on the required axis.

To stop such an addition taking the angle outside it's 0-359 degree range the WrapValue() function automatically wraps the value around when it gets to 360.

So if on the Y axis object 1 is currently at 350 degrees and you want to rotate it another 20 you would use:

YRotate Object 1,WrapValue(Object Angle Y(1)+20)

This would result in object 1's resulting angle being 10 degrees - not 370.

The same can be done in reverse using -20 instead of +20 to rotate an object in the opposite direction.

All of this is covered in the many tutorials on this web site. Check the stickies at the top of the Dark Basic board for some beginners tutorials as well as those at the top of this one.

I think you'll find he's more irritated that your question has no substance. It is courtesy to show what you have tried when you ask a question, rather than expect somebody to do all the work for you.

Also, most people will be much more willing to answer your questions if you have a useful thread title.

Useful:
"Problem with Angles"
"Can someone explain angles?"
"Angle Help"

NOT Useful, And will make most people regard you as a complete noob:
"Can u..."
"HELP!!"
"I need help!"
"Is this possible?"


"Ok, so that wasn't funny. I don' have any good Christmas jokes."

A simple question

randomize matrix command.
Even if I execute it how many times,
The same answer returns.

Is this right?

hmm, you are correct, it does give the same matrix every time

The matrix is different for me each time, so there's no problem with the code.

It might look similar because the matrix is only 4x4, but it is different each time.

RANDOMIZE timer() is invalid.
Understood; thank you.

DBC and DBP work different.

Oh OK - didn't realise that. I did only try it in DBC, so my apologies.

I ran some tests to show that the randomize timer() does produce random results in DBP, but does not work with randomize matrix. It is odd that it works in DBC but not DBP. Is it possible to generate a truly random matrix each time in DBP?

If you repeatedly call randomize matrix, it changes...so you could do it a random number of times, might be a bit slow though...

You forgot to include the 'sync' command in your loop

It is odd to have a do-loop that has nothing in it. Why not just use 'wait key' or something to that effect?

I'm not 100% certain with DBP, but (the previous reason for not requiring a Sync notwithstanding), doesn't Update Matrix automatically do a Sync anyway?

But sync refreshes the screen, AKA showing everything. That is why I got mixed up.

Quote: "
No, he didn't. You don't call SYNC without turning sync on first. And if you don't turn sync on, you don't need SYNC at all."


Sync is always on, unless commanded otherwise, with the Sync Off command. The same with the backdrop.

A theory of SYNC is simple.
However, SYNC of DBP is complicated.
SYNC is handled automatically.
Works of SYNC are different by conditions.
A combination of (text, 2D,3D).
Somebody,
I want you to explain automation of SYNC.

Yup - I think of it as the MANUAL SYNC FLAG. "Manual" Sync On and "Manual" Sync Off

A simple question

A part to a manual without explanation.

CLONE OBJECT ObjectNumber, SourceObject, Shared_Data_Flag
What is a meaning of "Flag"?

COMPILE CSG Input X File, Output X File, Epsilon
What is a meaning of "Epsilon"?
