My images are larger than they are supposed to be. Also, using multidimensional arrays and for-loops to put actors into the world.

Sorry for late reply. I've been busy.

You create objects in each part of the if-else-else... in your spawnPowerup method of the Powerups class; but, nothing is done with them.

I see... But problem is, addObject does not work in static methods. Any solutions? (Other than making the method non-static) I'm beginning to think that I should just make a simple randomiser... one that does not change the odds when something doesn't go the player's way... (In other words, I think I should give up on this complex randomiser. It's not a requirement and I'm making things more complicated than they have to be. Seems to be a habit of mine) Powerups

    public void spawnPowerup(int X, int Y){
         
        randChance = Greenfoot.getRandomNumber(100);
        if (randChance >= 0 && randChance < bombUpChance){

        else if (randChance >= explodeRadiusChance && randChance < oneUpChance){

BreakBlock

        powerupChance = 6;
        BombExplode explosion = (BombExplode) getOneIntersectingObject(BombExplode.class);

Easy, not really nice solution:

if (randChance >= (powerupChance-1))
{
    Powerups pUp = new Powerups();
    getWorld().addObject(pUp, getX(), getY());
    pUp.spawnPowerup(getX(), getY());
    getWorld().removeObject(pUp);
}

Better solution:

if (Greenfoot.getRandomNumber(6) == 0)
{
    randChance = Greenfoot.getRandomNumber(100);
    if (randChance < 30) getWorld().addObject(new BombUp(), getX(), getY());
    else if (randChance < 55) getWorld().addObject(new ExplodeRadius(), getX(), getY());
    else if (randChance < 65) getWorld().addObject(new OneUp(), getX(), getY());
    else getWorld().addObject(new Skate(), getX(), getY());
}

Even better solution

if (Greenfoot.getRandomNumber(6) == 0)
{
    randChance = Greenfoot.getRandomNumber(100);
    if (randChance < 30) getWorld().addObject(new Powerup(0), getX(), getY());
    else if (randChance < 55) getWorld().addObject(new Powerup(1), getX(), getY());
    else if (randChance < 65) getWorld().addObject(new Powerup(2), getX(), getY());
    else getWorld().addObject(new Powerup(3), getX(), getY());
}

(Which is the same as:

if (Greenfoot.getRandomNumber(6) == 0)
{
    randChance = Greenfoot.getRandomNumber(100);
    getWorld().addObject(new Powerup(randChance<30 ? 0 : randChance<55 ? 1 : randChance<65 ? 2 : 3), getX(), getY());
}

)

//Powerup class
private int type; public int getType() {return type}

public Powerup(int type)
{
    this.type = type;
}

//player checks collision with powerup
Powerup powerup = (Powerup) getOneIntersectingObject(Powerup.class);
if (powerup != null)
{
    switch (powerup.getType())
    {
        case 0: maxBomb++; break;
        case 1: explodeRadius++; break;
        case 2: lives++; break;
        case 3: moveSpeed -= 5; break; //bit weird that the variable is called “speed” but you decrease it to move faster
    }
    getWorld().removeObject(powerup);
}

Thanks Super Hippo, but unfortunately I have simplified it and made it less complex than my previous versions (and it works now). Sorry to make you go through that effort. Hopefully I (or someone looking at this page) will use your code as reference in future. Thanks anyway. Appreciate the effort. My apologies.

Haha yeah, it's just because the player's movement is "delayCount += moveSpeed", so the lower the moveSpeed is, the less delay between movements there is, so the faster the player goes. It's just so that the player doesn't move out of sync with being centred in the cells. It's also because I used code from my previous project (frogger) as inspiration.

All my problems (that I can think of) have been fixed, apart from two one: - Creating a 2D array and spawning in actors into the world (randomly) using the array (danpost made a suggestion on this that I am yet to try) - Problems with a switch statement that refuses to change an actor’s image (could be a problem with the variable not changing, I am unsure) Edit: this 2nd problem has been fixed.

I'm going to be honest here, I am getting quite annoyed at how Greenfoot can't seem to cope very well with loops. I created a for-loop (i=0, i < 35) and greenfoot crashed because of it. Seriously, something so simple should not be so much of a problem. Is anyone else having this problem? I keep noticing others using a for-loop inside a for-loop, but if I do that, Greenfoot crashes 101% of the time.

private void prepare()
    fillGrid(myGrid, Y);

//selector is equal to 20
public void fillGrid(String[][] grid, int ycoord){
        for (int i = 0; i < (grid[ycoord]).length;){
            if (grid[ycoord][i] == ""){
                int randInt = Greenfoot.getRandomNumber(selector);
                if (ycoord > 15 && selector > 17){
                    randInt = Greenfoot.getRandomNumber(selector)+20;
                    //increases the likelihood of key/door spawn.
                    //Otherwise, the likelihood of no endgoal spawn would be high.
                }
                
                
                if (randInt >= 18){
                    if (getObjects(Door.class).size() < 1){
                        grid[ycoord][i] = "DoorBlock";
                        addObject(new DoorBreakBlock(), (i*25+25/2), (ycoord*25+25/2));
                        selector--; //ensuring only 1 spawn
                    }
                    else{
                        grid[ycoord][i] = "KeyBlock";

                    }
                }
                else if (randInt < 17 && randInt > 9){
                    grid[ycoord][i] = "Enemy";
                    addObject(new Enemy(), (i*25+25/2), (ycoord*25+25/2));
                }
                else if (randInt >= 0 && randInt < 10){
                    grid[ycoord][i] = "BreakBlock";
                    addObject(new BreakBlock(), (i*25+25/2), (ycoord*25+25/2));

        }

Apparently, you do not know how to work with loops, yet (it is not Greenfoot that is at fault). Normally, you will have 3 parts to a standard for loop -- (1) the iterating variable with its initial value; (2) the condition for breaking out of the loop; and (3) what changes between each iteration of the loop (which is normally the change in value of the iterating variable; e.g. "i++"). You appear to be missing this last part, so your i value never increments in line 3 (it is forever 0, so you get stuck in your loop).

I remember hearing somewhere that the i++; was optional, and that, by default, if it was left blank then it would register it as i++ anyway. In some of my loops, there was no i++ included, and they still functioned as if i was increasing (they stopped at the correct amount). I'll have to mess around with this.

444Jam444

So... both for (int i = 0; i < num;){} and for (int i = 0; i < num; i++){} are valid and working statements that do the same things, but if you would rather not have a forever-crashing greenfoot, use for (int i = 0; i < num; i++){}. Thanks danpost. Without you, I would have had a very frustrating time trying to figure out why greenfoot continuously crashed. And to be fair, I was not wrong, but my way was not optimal (whatsoever).

Yes -- it is optional; however, it will not still register as i++ (your source was mistaken -- nowhere is that mentioned in the documentation).

In some of my loops, there was no i++ included, and they still functioned as if i was increasing (they stopped at the correct amount). I'll have to mess around with this.

You may have had an:

i++;

within the code block itself (or something comparable).
