a rectangle should be displayed at a specified position:

rect(xpos[5], ypos[9], boxh, boxh);

}

The box is always on the top left corner (0.0,0.0).

i wrote a little sketch:

before setup:

import ketai.data.;

KetaiSQLite db;

KetaiSQLite db;
String CREATE_DB_SQL = “CREATE TABLE data ( _id INTEGER PRIMARY KEY AUTOINCREMENT, punkte INTEGER NOT NULL DEFAULT ‘0’, level INTEGER NOT NULL DEFAULT ‘0’);”;

in setup:

db = new KetaiSQLite( this); db.connect();

if (!db.tableExists("data")){ db.execute(CREATE_DB_SQL);} db.query( "SELECT * FROM data" ); while (db.next()) { level=db.getInt("punkte"); punkte=db.getInt("level"); }

somewehere in the sketch:

if (!db.execute(“INSERT into data (`punkte`,`level`) VALUES (punkte, level )”)) println(“error w/sql insert”);

I get this error message:

Error executing sql statement: no such column: punkte (code 1): , while compiling: INSERT into data (`punkte`,`level`) VALUES(punkte, level )
error w/sql insert

I have some experience with MySQL and PHP, but i don't know what i'm doing wrong.

is there a way to find shapes or vertices in an simple black and white image?

Hello, i trying a little jump and run. The problem is when i set screensize to displayWidth and displayHeight you can see the box jumping. But when i set width and height to 800x480, you can not see the box jump.

This is my code:

float x,y,w,h,i;

void setup(){

}

void draw(){

size(800,480);

}

i found this example for multitouch:

Is there a way to send the x,y variables to the draw() function? Or to call them in draw()?

i found this little jumping example:

http://processing.org/reference/sin_.html

How can only display the positive wave?

how do you solve the problem of drawing with processing and different display sizes? On my galaxa S4 everything looks smaller than on my HTC Desire. How can i fit my sketches to all display sizes?

how can i use/access the menu button from Android Smartphones in a processing sketch?

how can i use this code in a processing sketch:  http://www.hascode.com/2010/04/sensor-fun-using-the-accelerometer-on-android/

This doesn't work:

How can i insert this in my processing sketch?

knuppel

i followed this instructions:  https://forum.processing.org/topic/how-to-including-ads-to-android-project to ad admob abds to a sketch. But this didn't work. Does anyone manage it to ad ads?

i'd like to do a little intro like:

...

...

...

...

The problem ist, that the text is no showen. 

The sketch has a blank screen for 6 5 seconds and then goes on.

Any help please?

i tried this example sketch:

http://www.learningprocessing.com/examples/chapter-8/example-8-2/

It creates two objects. 

How do i check if the two objects have the same coordinates?

how can i send some values to a php script out of processing?

Just like:  http://www.droidworker.com/xxxxxxxxxxx.php?name=Hans&points=10938

i have following sketch:

2. Car myCar1;
3. Car myCar2; // Two objects!
4. 
   
5. 
   
6. void setup() {
7.   size(400,800);
8.   // Parameters go inside the parentheses when the object is constructed.
9.   myCar1 = new Car(color(255,0,0),10,0,2); 
10.   myCar2 = new Car(color(0,0,255),100,0,1);
11. }
12. 
    
13. void draw() {
14.   background(255);
15.   myCar1.drive();
16.   myCar1.display();
17.   myCar2.drive();
18.   myCar2.display();
19. }
20. 
    
21. // Even though there are multiple objects, we still only need one class. 
22. // No matter how many cookies we make, only one cookie cutter is needed.
23. class Car { 
24.   color c;
25.   float xpos;
26.   float ypos;
27.   float xspeed;
28. 
    
29.   // The Constructor is defined with arguments.
30.   Car(color tempC, float tempXpos, float tempYpos, float tempXspeed) { 
31.     c = tempC;
32.     xpos = tempXpos;
33.     ypos = tempYpos;
34.     xspeed = tempXspeed;
35.   }
36. 
    
37.   void display() {
38.     stroke(0);
39.     fill(c);
40.     rectMode(CENTER);
41.     rect(xpos,ypos,75,75);
42.   }
43. 
    
44.   void drive() {
45.     
46.     ypos = ypos + xspeed;
47.     if (ypos > height) {
48.       ypos = 0;
49.     }
50.   }
51. }

Now I'd like to set the ypos to 0 when you touch this objects on your smartphone.

How can i solve this?

I tried if(mouseX=xpos && mouseY=ypos)....but this didn't work.

My question is, how can i insert data in a table?

I tried this:

Share your processing sketches online: http://www.opensketches.org

http://www.opensketches.org/arduinobluetoothprocessing-arduino-android-bluetooth-communication/

The app crashes on my smartphone (Android 2.2.2), i also tried it with android 2.3 which didn't work, too.

Any suggestion. Can i use Ketai with Android 2.2.2 or 2.3?
