move just one time
Put the condition (using an 'if' statement) on the call to 'move'.
if (Greenfoot.mouseClicked(this)) move();
yh i had alreay do that, but with the keyboard... "left" to move left and "right" to move right
but the problem is that i want that the object move 50 cells per move, but with the method: isKeyDown always that i press the keyboard the objets move 1 time per act and not 1 time per click
yh, erdelf, i had done that already too, but dont work becouse i'm using the method isKeyDown to fire...
You can use 'isKeyDown' with a boolean to track the state of the keys:
The else part waits for both direction keys to be not in a pressed state before resetting the field.
// instance field
private boolean dirKeyDown; // direction keys state
// code
if (!dirKeyDown)
{
if (Greenfoot.isKeyDown("right"))
{
move(1);
dirKeyDown = true;
}
if (Greenfoot.isKeyDown("left"))
{
move(-1);
dirKeyDown = true;
}
}
else if (!Greenfoot.isKeyDown("right") && !Greenfoot.isKeyDown("left")) dirKeyDown = false;works great thank you man:)
