So I was working on my code, which is to draw three bees, and each time they bounce on to wall or hive, they would bounce back(aka change their direction), while I have done that without any problem, I was trying to apply scale function, where they would increase the size depend on number generated randomly from 2-4. And I used scale() function, but the problem is that it also changed the beginning location of bee, and for some reason, they don’t bounce back. I have been working on it for good few hours, and still can’t figure out why can anyone help me with this problem?

Here is the code I used:  
void setup() {  
size(800, 800);  
beeX1 = width/2; beeY1=height/2;  
beeX2 = width/2; beeY2=height/2;  
beeX3 = width/2; beeY3=height/2;  
combX = width_2/3; combY = height_2/3;  
}  
float beeX1, beeY1;  
float beeX2, beeY2;  
float beeX3, beeY3;  
int beeDX1=1, beeDY1=1;  
int beeDX2=-1, beeDY2=1;  
int beeDX3=1, beeDY3=-1;  
int count=0;  
float combX, combY;  
boolean bCrash1=false, bCrash2=false, bCrash3=false;  
int r1=int(random(2,5));  
int r2=1;//int(random(2,4));  
int r3=1;//int(random(2,4));  
void draw() {  
background(200, 250, 50);

drawHoneycomb(combX, combY, count);

beeX1+=2_beeDX1;  
if(beeX1+20\>width || beeX1-20\<0) {beeDX1 = -beeDX1; bCrash1=false;}  
beeY1+=3_beeDY1;  
if(beeY1+20\>height || beeY1-20\<0) {beeDY1 = -beeDY1; bCrash1=false;}  
drawBee(beeX1, beeY1,r1);

beeX2+=2_beeDX2;  
if(beeX2+20\>width || beeX2-20\<0) beeDX2 = -beeDX2;  
beeY2+=1_beeDY2;  
if(beeY2+20\>height || beeY2-20\<0) beeDY2 = -beeDY2;  
drawBee(beeX2, beeY2,r2);

beeX3+=3_beeDX3;  
if(beeX3+20\>width || beeX3-20\<0) beeDX3 = -beeDX3;  
beeY3+=2_beeDY3;  
if(beeY3+20\>height || beeY3-20\<0) beeDY3 = -beeDY3;  
drawBee(beeX3, beeY3,r3);

if(beeY1+20 \> combY-40 && beeY1-20 \< combY+40 && beeX1+20 \> combX-40 && beeX1-20 \< combX+40 ) {  
beeDX1 = -beeDX1;  
beeDY1 = -beeDY1;  
count++;  
}  
if(beeY2+20 \> combY-40 && beeY2-20 \< combY+40 && beeX2+20 \> combX-40 && beeX2-20 \< combX+40 ) {  
beeDX2 = -beeDX2;  
beeDY2 = -beeDY2;  
count++;  
}  
if(beeY3+20 \> combY-40 && beeY3-20 \< combY+40 && beeX3+20 \> combX-40 && beeX3-20 \< combX+40 ) {  
beeDX3 = -beeDX3;  
beeDY3 = -beeDY3;  
count++;  
}

}

void drawBee(float bx, float by, int scale) {  
pushMatrix();  
scale(scale);  
fill(255, 255, 0);  
ellipse(bx, by-15, 12, 6);

ellipse(bx+12, by+3, 16, 10);  
popMatrix();  
}

void drawHoneycomb(float hx, float hy, int count) {  
int maxX=3, maxY=6;  
for(float j=0; j\<maxY; j++) {  
for(float i=0; i\<maxX; i++) {

Hi @Fungineer1 Welcome to the forum.  
Please edit your post above by clicking on the pencil.  
Then select all your code and click on the \</\> button in the editing box.  
To scale the bee you’ll first have to [make a shape of the whole bee](https://processing.org/reference/PShape_addChild_.html), and then apply the scale() function on that shape in draw().
