You just have to use a boolean that is set true if your character tuches the gun:

private boolean gunTuched = false;

public void act() {
    if (getOneIntersectingObject(Gun.class) != null)) {
        gunTuched = true;
    }
    if (gunTuched /*and probably more conditions you can add here*/) {
        shoot();
    }
}

If your gun class isn't called Gun you have to change the name in line 4. And if your character should just be able to shoot if he is still tuching the gun you need to change it like this:

//you don't need the boolean anymore;
public void act() {
    if (getOneIntersectingObject(Gun.class) != null) {
        //the other conditions for shooting;
        shoot();
    }
}

// if you currently have in your character act method
shoot(); 
// then qualify it with
if (getOneIntersectingObject(Gun.class) != null) shoot();

}

I want the gun to disappear when we touches it and be able to continue to shoot. The gun wont be with him. Basically the gun enable him to shoot once he touches it once.

In this case you have to use the first peace of code I gave you. And you should make the gun dispear after your character has set activated his gun.

If I place your code then my character can only shoot when he touching the gun. I want it to be able to shoot once to touches the gun only once, then gun disappears.

Can you post your code? I'm not shure why this occurs.

public boolean gunTouched()
{
Actor gun = getOneIntersectingObject(Gun.class);
if(a!=null)
{
getWorld().removeObject(gun);
return true;
}
else
return false;
}

If you put this into the act-method it will return false in the next act, after returning true.

Or you do it like this:

boolean shootAllowed = false;

public void gunTouched()  
{  
Actor gun = getOneIntersectingObject(Gun.class);  if(a!=null)  
{ 
getWorld().removeObject(gun);  
shootAllowed = true; 
}  
else  
shootAllowed = false;  
}

And then write it in the act method like this:

public void act()
{
gunTouched();
if(shootAllowed && Greenfoot.isKeyDown("space")) 
//or how you want make the player to shoot
{
shoot();
shootAllowed=false;
}
}

If you make it like this way, the player has infinite time to shoot, but after shooting he can't shoot again until he finds the next weapon to pick up or how it should work later.
