In the code for that actor you want to go up and down, in the act() method, put your if statement with your turn() and move() statements. If after trying that, and fidgiting with it, and you still cannot get it to work, post your code with a specific question of what you are trying to do.
I am trying to get a person to move to right, left, up, down when the following key is pressed. I can get left and right but I can't get up and down to work. If I use the below it just turns. If I separate the move and put it after the curly bracket when i press run it just does the move command.
{
if (Greenfoot.isKeyDown("up") )
{
turn(-4);
move(4);
}
1 2 3 4 5 6 7 8 9 | int speed = 3;if(Greenfoot.isKeyDown("up")) setLocation(getX(), getY() - speed);if(Greenfoot.isKeyDown("down")) setLocation(getX(), getY() + speed);if(Greenfoot.isKeyDown("left")) setLocation(getX() - speed, getY());if(Greenfoot.isKeyDown("right")) setLocation(getX() + speed, getY()); |
