I've managed to get the character to jump using spacebar key but the jump is active for far too long and the character goes to the top of the screen. could someone take a look: http://www.greenfoot.org/scenarios/8881

Jump active for far too long
done one better the source code is available.
Okay first of all you changed my checkGround() method.. The one i created would actually return true when mario was on the ground which makes your task a whole lot easier :)
Okay so I changed a lot of methods, but only minor stuff, and to danpost before you start rewriting my 10 lines of code into 2, I know there is a smoother way.
public void act()
{
checkKeys();
if(!checkGround())
{
fall();
}
else
{
jumping = false;
}
}public void jump()
{
vSpeed = vSpeed - jumpDistance;
fall();
}public boolean checkGround()
{
Actor marioLeftFoot = getOneObjectAtOffset(-19, marioHeight, Tile.class);
Actor marioRightFoot = getOneObjectAtOffset(19, marioHeight, Tile.class);
if (marioLeftFoot == null && marioRightFoot == null)
{
return false;
}
marioLeftFoot = getOneObjectAtOffset(-19, marioHeight - 1, Tile.class);
marioRightFoot = getOneObjectAtOffset(19, marioHeight - 1, Tile.class);
while (marioLeftFoot != null || marioRightFoot != null)
{
setLocation(getX(), getY() - 1);
marioLeftFoot = getOneObjectAtOffset(-19, marioHeight - 1, Tile.class);
marioRightFoot = getOneObjectAtOffset(19, marioHeight - 1, Tile.class);
}
vSpeed = 0;
return true;
} Thanks Zamoht it works great.
