Question with void key pressed

in Programming Questions • 1 month ago

I created a "zoog" for my class and I now have to make it move in relation with the arrow keys.

Please Help?

float eyeR;

float eyeG;

float eyeB;

float X= random(30,190);

float Y= random(30,100);

void setup(){

size(200,200);

frameRate(5);

X= X;

Y= Y;

}

void draw(){

background(0);//Draw a black background

float X= random(30,170);

float Y= random(30,100);

//Set ellipses and triangles to CENTER

ellipseMode(CENTER);

rectMode(CENTER);

//Zoog's body

stroke(39,242,29);

fill(255);

triangle(X,Y,X+30,Y+80,X-30,Y+80);

//Zoog's head

fill(39,242,29);

ellipse(X+0,Y+5,60,60);

stroke(127);

line(X+10,Y+20,X-10,Y+20);

//Zoog's eyes

eyeR=random(255);

eyeG=random(255);

eyeB=random(255);

fill(eyeR,eyeG,eyeB);

ellipse(X-19,Y+0,16,25);

ellipse(X+19,Y+0,16,25);

//Zoog's Legs

stroke(255);

line(X-10,Y+80,X-20,Y+100);

line(X-20,Y+100,X-10,Y+60);

line(X+10,Y+80,X+20,Y+100);

line(X+20,Y+100,X+10,Y+50);

}

Well, indeed, use the keyPressed() function. There, you can update X and Y, depending on the key the user pressed.

X= X;
Y= Y;

Uh? Useless lines...

float X= random(30,170);
float Y= random(30,100);

Are you aware you define new variables, here, hiding the global ones? Remove the float from these lines.

it says there is an unexpected token void(regarding the void keyPressed)

thank you for the feedback

if(arrow buttons are pressed){arrow=false;}{Else{button=true;}

Java language doesn't allow nested functions. That is, we can't put a function inside another function!
That is what you just did w/ functions keyPressed() & draw(), all of them inside function setup()!
Use <CTRL> + <T> to reformat your text code to better visualize it.

Yes, as said, add a } after the frameRate() call.
And comment out the last line, in pseudo-code.
