selectInput for a 3D... beginner

in Programming Questions • 9 months ago

Hellooooooo everyone

I'm trying to make a selectInput() for a PShape in my code (to load a 3D).. and that's not working :(

I've got a first 3D, (MTECH.obj) to make a demo of the software, and i need it when the software open, and i want the selectInput() to change it.

Can you help me just a little bit :D
It's the only thing i need to finish it ^^

Thank to everyone!! (and sorry for english, i'm french)

this might help you:

//

// create a file chooser
final JFileChooser fc = new JFileChooser();
// create file
java.io.File thisFile;
//
String[] list;
java.io.File file1;
// ========================================================================================================
void setup () {
// Init
size (1230, 800, P3D );
background(0);
// create a dir of the sktch dir
thisFile = new java.io.File(sketchPath(""), "");
// set this dir as default dir of the fc
fc.setCurrentDirectory(thisFile);
loadFile () ;
if (file1!=null)
println(file1);
if (list!=null)
println(list);
}
//
void loadFile () {
// in response to a button click:
int returnVal1 = fc.showOpenDialog(this);
if (returnVal1 == JFileChooser.APPROVE_OPTION) {
file1 = fc.getSelectedFile();
list = loadStrings(file1); // load text file into array
}
else {
println("Open command cancelled by user. - ");
// exit();
}

Thank you but i already test this one, and it's older than selectInpput().

I just want to know the part of code that i miss..?

Re: selectInput for a 3D... beginner

sorry, I can't run it........
Renderer = ?

and it's way over my head I think. Sorry!

[edited]

In line 13 you got Importer and your function line 115 has the same name? Bad?

You must call Importer in line 36.

In line 116 you need a var to store the result:

File fileName = selectInput("Select a file to process:", "fileselected");

After line 116 say

fileSelected(fileName);

or so.

I am not sure.

Re: selectInput for a 3D... beginner

I'm trying to make a selectInput() for a PShape in my code (to load a 3D).. and that's not working :(

What goes wrong?

Looking at your code you need to call the Importer method to execute the selectInput and I can't find it.

The slectInput requires a callback function which will be used to load the file in a separate thread. This should be referred to by a local variable and only transfer to the global on success. e.g.

void fileSelected(File selection) {
if (selection == null) {
println("Window was closed or the user hit cancel.");
}
else {
println("User selected " + selection.getAbsolutePath());
Shape temp = loadShape(selection.getAbsolutePath());
if(temp != null)
s = temp;
}
}

Because this is in a separate thread s will not be changed to the loaded shape immediately after the selectInput has completed - there will be a delay before you can use the loaded shape in the main thread.

BTW I am unable to run your code because I must be missing some libraries that you are using.
