My final project is to have several shapes, several colors, an object that moves independent and an object that moves dependent of the user, etc. etc.

Here's what I have code-wise: 

2. //Steve
3. int xPs= 0; 
4. int yPs= 0;
5. int rAs=0;
6. int sPs=1;  
7. int imageNumber = 0; 
8. Cloud Cloud1;
9. //********************************************************************************
10. void setup() {
11.   size (500, 500);
12.   frameRate(15);
13.   background(#9CE5EA);
14.   Cloud1 = new Cloud(color(255,0,0),0,100,2);
15. }
16. //********************************************************************************
17. void draw() {
18.   background(#9CE5EA);
19.   Steve(xPs, yPs, rAs, sPs, imageNumber);
20.   Cloud1.move();
21.   Cloud1.display();
22. }
23. //********************************************************************************
24. 
    
25. void Steve(int xPs, int yPs, int rPs, int sPs, int i) {
26.   
27.   pushMatrix();
28.   translate(250, 250);
29.   scale(2); 
30.   stroke(#000000);
31.       if (imageNumber == 0) {
32.       //  first image
33.       quad(0, 0, 20, -20, 30, -10, 10, 10);
34.       quad(0, 0, -20, -20, -30, -10, -10, 10);
35.       rect(-12, -12, 25, 35);
36.       ellipse(0, -23, 30, 30);
37.       rect(-12, 23, 13, 20);
38.       rect(0, 23, 13, 20);
39.       imageNumber= imageNumber + 1;
40.       
41.     } else if (imageNumber == 4){
42.       //Mid image 2
43.       rect(-35,-5, 70, 15);
44.       rect(-12, -12, 25, 35);
45.       ellipse(0, -23, 30, 30);
46.       rect(-12, 23, 13, 20);
47.       rect(0, 23, 13, 20);
48.       imageNumber = 0;
49.       
50.     } else if (imageNumber == 1){
51.       //Mid image
52.       rect(-35,-5, 70, 15);
53.       rect(-12, -12, 25, 35);
54.       ellipse(0, -23, 30, 30);
55.       rect(-12, 23, 13, 20);
56.       rect(0, 23, 13, 20);
57.       imageNumber = 2;
58.       
59.     }else if (imageNumber == 2){ 
60.       // second image
61.       background(#9CE5EA);
62.       quad(0, 0, 10, -10, 28, 15, 18, 23);
63.       quad(0, 0, -10, -10, -28, 15, -18, 23);
64.       rect(-12, -12, 25, 35);
65.       ellipse(0, -23, 30, 30);
66.       rect(-12, 23, 13, 20);
67.       rect(0, 23, 13, 20);
68.       imageNumber = 4;
69.     }
70.    popMatrix();
71. 
    
72. }
73. //******************************************************************************
74. class Cloud {
75.   color c;
76.   float xpos;
77.   float ypos;
78.   
79.   
80.   Cloud(color tempC, float tempXpos, float tempYpos, float tempXspeed){
81.   c = tempC;
82.   xpos = tempXpos;
83.   ypos = tempYpos;
84. 
    
85. }
86. void display (){
87.   pushMatrix();
88.   translate(100, 100);
89.   scale(2); 
90.   stroke(#FFFFFF);
91.   ellipse(-7, -3, 25, 25);
92.   ellipse(7, -3, 25, 25);
93.   ellipse(15, 10, 20, 20);
94.   ellipse(0, 10, 20, 20);
95.   ellipse(-15, 10, 20, 20);
96.   popMatrix(); 
97. }
98. 
    
99. void move() {
100.     
101.     if (xpos > width) {
102.       xpos = xpos + 20; 
103.     }
104.   }
105. }

If it wasn't really clear already, I have little knowledge of what I'm doing. 
My goal is to have the man (steve) fall unless holding the mouse key, and having the cloud move to the right in the background. The code above is before I started messing around trying to get the cloud to move, and I was wondering if anyone could help me
-get the cloud to move to the right slowly

-get the man to fall if the mouse is not held

Thanks in advance!
