I am coding for an assignment and I am having a hard time. I want to make a shape, then particles, change between red. yellow and blue by hitting keys. I can’t tell what I’m doing wrong. Please help!

float offset =180;  
boolean isKeyPressedLeft = false;  
boolean isKeyPressedDown= false;  
boolean isKeyPressedRight= false;

float centerX;  
float centerY;

void setup()  
{  
size(200, 200);  
centerX= width / 2.0f;  
centerY = height /2.0f;  
}

void draw ()  
{  
background (63);  
circle (100, 100, 100);  
noStroke();

if (isKeyPressedLeft)  
fill ( 228, 46,46);

if (isKeyPressedDown)  
fill ( 237, 201,41);

if (isKeyPressedRight)  
fill( 56, 76, 228);  
}

void keyPressed()  
{  
updateKeyboard(true);  
}

void keyReleased()  
{  
updateKeyboard(false);  
}

void updateKeyboard(boolean state)  
{  
if (keyCode ==LEFT)  
isKeyPressedLeft = state;  
if (keyCode ==DOWN)  
isKeyPressedLeft = state;  
if(keyCode == RIGHT)  
isKeyPressedLeft = state;  
}

Hi @karbon Welcome to the forum.  
In the updateKeyboard() function you are using the same boolean for all keyCodes  
Change them like:

```auto
if (keyCode == LEFT) isKeyPressedLeft = state;
if (keyCode == DOWN) isKeyPressedDown = state;
if (keyCode == RIGHT) isKeyPressedRight = state;

```
