Using getX & getY in world?
As I asked you, do you call the method getKey somewhere else in your code? Because the getKey method works that, once a key is pressed, it 'remembers' that until someone calls that method. Once it is called, it forgets that key again and will return null from that point on, until a new key is pressed. That's the only thing I can think of now that might cause this.
That's the only place where I call the getKey method so I'm not quite sure what's going on
I have a feeling (without checking) that this may be a "case" problem. Try using:
with a lowercase 'v'. I believe the getKey method returns the specific case sent to it, where the 'isKeyDown' method always sets the same case for both the key pressed and the key asked for (the press of the key could be for either case).
if ("v".equals(Greenfoot.getKey()))Well now I have ran into a problem as I've realised that it only works with 1 player, how would I only allow 1 bullet to fire with 2 players?

private boolean shotKeyDown;
// in act method or a method it calls
if (shotKeyDown != Greenfoot.isKeyDown(shotkey)) // shotkey = "v" for player one
{
shotKeyDown = !shotKeyDown; // save changed state
if (shotKeyDown) // changing to down state?
{
// shoot code here
}

Thanks, so I had to use both methods, gotchaI am trying to create respawn methods for both virus (VirusWASD & VirusARROW) after they are killed and am having some trouble. The current code I have, spawns a virus even if the equivalent survivor is not infected yet. The current code also only has VirusWASD, not quite sure how to add VirusARROW into the same method (if possible)
Respawn Code:
Reminder of Infect code:
Thanks in advance :)
P.s How would I be able to spawn it in different defined locations (not random)?
public void respawn()
{
if (getObjects(VirusWASD.class).size() == 0)
{
addObject(new VirusWASD(),173 ,429);
}
} private void infect()
{
if (Greenfoot.mouseClicked(twoPlayer_Button)) // countdown starting
{
countdown = 16; //2276
}
if (countdown == 0) return; // countdown already completed
countdown--;
if (countdown == 0) // countdown just completed
{
setPaintOrder(InfectionHasStarted.class, GameTimerGif.class, TimerBackground.class);
addObject(new InfectionHasStarted(), 695, 393);
addObject(new TimerBackground(), 691, 47);
addObject(new GameTimerGif(), 687, 48);
Actor[] viruses = new Actor[] { new VirusWASD(), new VirusARROW() }; // must be same order as 'survivors'
int chosen = Greenfoot.getRandomNumber(2);
addObject(viruses[chosen], survivors[chosen].getX(), survivors[chosen].getY());
removeObject(survivors[chosen]);
respawn();
//removeObject(twoPlayer_Button); // optional
}These "different defined locations", are they to be used in order as defined, or randomly among those defined? (it is unclear as to how "(not random)" is being used here). At any rate, the locations can be defined in a double int array:
For cycling through the locations, you will need an int field that is increments and reset to zero when all locations have been used for the index in the array instead of the 'rand' value.
// for example
int[][] locs = { { 173, 429 }, { 252, 357 }, { 211, 499 } };
// a random location choice would be
int rand = Greenfoot.getRandomNumber(locs.length);
int x = locs[rand][0];
int y = locs[rand][1];
addObject(new VirusWASD(), x, y);Yeah, I meant defined locations that are random among those defined. How would I make sure the Virus only respawns if the equivalent Survivor is infected?

I understand but this would result in 2 viruses spawning(if infected) or a random virus spawning when its not mean to
