[Solved] Recalling an int, gives an "empty" spot.

[roseslayer]

Hello all,
It's me again and I got a small question: Does anyone know the best way to recalling an int that was made with a "for" line? I'm currently using a code where I am doing this:

1	Screen.room.block[blockY][blockX] = Screen.room.block[y][x];

The only problem is, the previous blockY and blockX are "empty" when you press your LMB. the airID and the groundID are 0 when I press my LMB. I need to "recall" the ints for another script, because when I upgrade a tower it needs to know where to upgrade. My code can be a little bit odd. I'm fairly new to programming.
my whole code:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33

if(mouseButton == 1) {          for(int y = 0; y<Screen.room.block.length;y++) {             for(int x = 0; x<Screen.room.block[0].length;x++) {                if(Screen.room.block[y][x].contains(Screen.mse)){                   Screen.room.block[y][x].rangeVisible = true;                   Screen.room.block[blockY][blockX] = Screen.room.block[y][x];                          if(Screen.room.block[y][x].airID >= 2 && Screen.room.block[y][x].airID <= 7){upgradeScreen = Screen.room.block[y][x].airID -1; upgradeStore = true;}else{upgradeStore = false; upgradeScreen =0;}                } else {                   Screen.room.block[y][x].rangeVisible = false;                }             }          }          if(upgradeStore == true){             for(int i=0;i<upgradeButton.length;i++) {                if(upgradeButton[i].contains(Screen.mse)) {                   if(upgradeButtonID[i] != Value.airAir) {                      if(upgradeButtonID[i] == Value.airUpgrade) {                         if(Screen.money >= upgradePrice){                            if(Screen.room.block[blockY][blockX].airID != 4 ){                               Screen.room.block[blockY][blockX].airID += 1;                               Screen.money -= upgradePrice;                               upgradeScreen += 1;                            }                         }                      }                      if(upgradeButtonID[i] == Value.airSell){                          Screen.room.block[blockY][blockX].sell();                         Screen.money += sellPrice;                      }                   }                }             }          }

Already thanks!

I'm not sure I entirely understand your question, but can't you just make a variable that stores it?

for example StoredX and StoredY? and then use those?

I thought to do that the same, so i made blockX and blockY as store places. only when the store gets his first x and y, the blockX and blockY (that are 0 at start) are changing to x and Y (2 and 3 as example so blockX = 2 and blockY =3, but the other values 0,0 are gone and so are the groundID and the airID of that block.
if i change the blockY on start to 3 and blockX to 3 then at (2,2) there's an "empty" spot, do you understand this better? cause I don't know how I can explain it good.

There is a few solutions you can do.

1) You can store an array of ints if you need the previous values for multiple entries.

2) I think an easier solution might be to have a boolean within the Screen.class like

boolean upgrade

. You can iterate through the loop and whatever

Screen

needs the upgrade will be automatically updated, then set that variable to false afterward.

3) If it needs to be updated to a certain point. You can store

int upgrade

in the Screen.class instead. This way you'll be able to tell a tower exactly how far you want it to upgrade. If the tower isn't at the number upgrade in the Screen.class, then it is time to upgrade it.

[EDIT]
Solved it,

Screen.room.block[blockY][blockX] = Screen.room.block[y]

• ;

that needs to be
{blockY=y; blockX=x;}
