so far I have managed to solve a lot of little bugs, mostly typos and the like. Here is a new one that is currently baffling me. After finally getting a 'bouncing ball' class to work (I call it a "banana"), I am confused about why it will not work within an if statement. The setup() and draw() blocks are below. The class works and I know this is true because if I call newBanana.display(); and newBanana.move(); on line 23 it works. 

However, I want to call these functions on lines 36 & 37 and here they do not work. Everything else in this statement works. I have put in print functions and they print when the conditional is met. But the function calls do not work. I have also tried reinstantiating(?) the class on line 35 (newBanana = new Banana();) but that also did not work. 

I'm sure its easy and hopefully I'll figure it out before someone tells me the answer. :)

2. Car myCar; // A Car
3. Grape newGrape; // A Grape
4. Banana newBanana; // A Bananna
5. 
   
6. int hitCount = 0; // Counter for how many times the grape has been hit
7. int carSpeed = 7;
8. 
   
9. void setup() {
10.   size(500, 500);
11.   myCar = new Car();
12.   newGrape = new Grape();
13.   newBanana = new Banana();
14. }
15. void draw() {
16.   background(255);
17.   //
18.   text (hitCount, width - 50, height - 20); // place HUD in bottom right corner
19.   fill(0);
20.   newGrape.display(); // draw a grape randomly on the screen
21.   myCar.display();    // Car starts in the middle of the screen
22.   myCar.move();       // Move the car where the user wants
23. 
    
24. 
    
25. 
    
26.   // Checks for collision between grape and car
27.   // Grape must be fully within the boundries of the car to be considered "hit"
28. 
    
29.   if (rectangle_collision (myCar.xpos, myCar.ypos, myCar.sizeW, myCar.sizeH, 
30.   newGrape.xpos, newGrape.ypos, newGrape.sizeW, newGrape.sizeH)) {  
31.     hitCount = hitCount + 1; // increase hit counter by 1
32.     if (hitCount == 10) {
33.       hitCount = 0;
34.       newGrape.kill();
35.       
36.       newBanana.display();
37.       newBanana.move();
38.     } 
39.     else {
40.       newGrape = new Grape();  // Grape redraws in a random location.
41.     }
42.   }

I've been googling and searching these forums for about an hour and I haven't been able to solve this problem.

I have a small "car" that moves around the screen and I want it to hit a "grape". I would like that grape to disappear and reappear somewhere else. 

I am new to processing and I don't really understand the differences between processing and processing.js but if I could find a tutorial like this one for Processing, that would be amazing!

My code is long and I know that this topic must have been covered already in a clear and concise manner, but I can not find it. 

Let me know if I need to post my code. 

Thanks!

I am new to processing and relatively new to coding. I am working through the examples on the site and have adapted one to try and learn from it. 

I would like to draw a single column of squares. I am currently getting the error 'invalid token: int' referring to the first couple of lines. What do you think? Thanks!
