Unexpected Character in class problem

in Programming Questions • 2 years ago

Ok… I just got into "Object Oriented Programing" AKA using classes and objects and I am getting an error in the class(not

surprised) and the tutorial isn't helping

I'm trying to make it so the ship moves left and right when the arrow keys are pressed (this is the start to a game type thing)

but I get "unexpected token: ("

From other examples I have seen, you need something in the "()" in the "Ship()"

Here is the class:

class Ship {

int x // x poistion of ship

Ship() { // THIS IS WHERE THE ERROR IS

x = 255

}

void show{

fill(255);

triangle(30+x,75,58+x,10,86+x,75);

}

void keys {

if(keyPressed && key == LEFT){

x = x + 50;

}

else if(keyPressed && key == RIGHT);{

x = x - 50

}

else(){

}

You have a serious lack of semicolons and parentheses, and then appear to place them where they do not belong.
Here is a revised (and neater) version of your code with fixes identified:

class Ship {
int x; // x poistion of ship //SEMICOLON HERE
Ship() {
x = 255; //SEMICOLON HERE
}
void show() { //PARENTHESES HERE
fill(255);
triangle(30+x, 75, 58+x, 10, 86+x, 75);
}
void keys() { //PARENTHESES HERE
if (keyPressed && key == LEFT) {
x = x + 50;
}
else if (keyPressed && key == RIGHT) { //REMOVE SEMICOLON HERE
x = x - 50; //SEMICOLON HERE
}
else { //REMOVE PARENTHESES HERE
}
}
}

Original code could almost compile with a Scala compiler... :-)

Thanks! (I usually don't screw up semi colons and parentheses, must have not been paying attention to that)
