ENDFUNCTION


at the moment i try to draw 10 'x' that why the dimension is 10....
let say i want to use just a constraint first rather than jumping directly to what i have plan for my application...
so i just try to make the xmark is drawn only when the "m" button is pressed...so i have tried :

a)

Code (glbasic) Select Expand

if key(50)=true
     make3dmarking(n)
endif


this command work but the xmark only appear when the "m" button is pressed and hold...if the we release the button, the xmark will disappear...so there will only be 1 'x'..

b)

Code (glbasic) Select Expand

if key(50)= true
  i=i+1
endif

make3dmarking(i)

i execute this but nothing appeared...

this is as far i get right now...im still trying...any help?

mars_chaos89, I wrote that code for you mate. Tell me you missed it!

[mars_chaos89]

i hav try execute the code..but it some error occur....

Code (glbasic) Select Expand

CONSTANT KEY_SPACE=57
CONSTANT KEY_X=45
CONSTANT KEY_Y=21
CONSTANT KEY_Z=44
CONSTANT KEY_LEFT=203
CONSTANT KEY_RIGHT=205
CONSTANT KEY_UP=200
CONSTANT KEY_DOWN=208

ti show that the error is here.....

[matchy]

That's odd. Please post the error!

[mars_chaos89]

"3d selection.gbas"(23) error : syntax error

this is the error....

[matchy]

CONSTANT seems to work fine with compiling with me. Besides, they only declare the key-codes and is irrelevant to the issue. By now you should have changed them to GLOBAL for now.

I've attached the project source with an exe:

i have changed it but something else happen...

this error come up..


i also have see what your program do...but that not exactly what i want to do...

this is my full code...what i want to do is put the 'x' mark on that donut model as many as we want...and save it...

At http://www.glbasic.com/forum/index.php?topic=4738.msg35786#msg35786 there's a really helpful post about a flow diagram program (free!) which might help find where the problem in your logic is. I'm stuck on a netbook at the moment which is not the very best for studying someone else's code on but based on previous posts it looks like you're not fully "getting" the way you need to pull the 3D model, the concept of an array of marker positions, the keypresses, and a disply loop (that displays the aircraft/doughnut, all previous X marks, and the current "floating" X mark) together.

I doubt I could draw a good chart using this screen either, but here's my thoughts in a "level at a time" manner.

First you have to decalre all your variables and set them to useful/default values.

In the outside / main loop you should display your main model. If any X's have been set you should display those. If an X has been activated but not fixed in place you should display it (differently to fixed X's IMHO).

Within the loop, either before or after displaying, you should check for keypresses. If the key is "make an X" then increase the number of X's, set the initial position of the new X.

ELSE If the key is a "move X" key then change the position of the current/last X mark.

ELSE If the key is a "set X position" then deal with that event (may be the same as the "create new X key, in which case this doesn't need writing).

ELSE If the key is a camera movement key then move the camera.

At the moment, although this may be partly because I can see so little code at a time on this tiny screen, I can't see how you are displaying all the pre-set X's as you think about setting a new one. Apologies if it's all present and correct and I am just failing to see it

A flowchart might be easier to study, and might enlighten you as to where things are going wrong as you create the chart anyway
