Space Invaders help!

Hi

I am trying to enhance a version of space invaders for an assignment and i have managed to align the 'aliens' in a row, but i cant work out how to get multiple rows underneath the first row (x).

I have tried x+1 and various others but i am stuck, can anyone help please?

Thanks in advance :D

it might help to see some of the relevant bits of code, inside code tags,

i'm pretty new but can i ask are you using two nested for loops to set them out

Hi thanks for the help :D

ill post the code i have that aligns the first horizontal row of 6 of the aliens.

public void initWorld() {
actors = new ArrayList();
for (int i = 0; i < 6; i++){ // amount of vertical space invaders
Monster m = new Monster(this);
m.setX( (int)(Stage.HEIGHT) );
m.setX( i*70 ); //width gap between space invaders
m.setVx( (int)(15-10) );

actors.add(m);

i need to do another 5 rows of aliens underneath this but im not sure how to shift the rows down by 1 each time, if that makes sense?

like I said im still new to this but i think you nedd to do something like this

Code:

---

public void initWorld() {
actors = new ArrayList();
for (int k =0: k <5; k++) { // sets out 5 rows
for (int i = 0; i < 6; i++){ // amount of vertical space invaders

Monster m = new Monster(this);
m.setX( (int)(Stage.HEIGHT) );
m.setX( i*70 ); //width gap between space invaders
m.setVx( (int)(15-10) );

actors.add(m);

}
}
you may need to use the K index somewhere to set out the height in the vertical.

hope this helps

i tried to put the 'k' in like you said but it hasnt made the extra rows i need. would i have to put the k index in one of the other classes too? or define it somewhere else?

not sure really, has it set out the rows on top of each other? so it loooks like one row.

you have used the index i

Code:

---

m.setX( i*70 ); //width gap between space invaders

---

presumably this sets a distance across from left to right

you will have to use the k index to set out the vertical distances

does this bit have something to do with the vertical spacing

Code:

---

m.setVx( (int)(15-10)
