Here´s what I have:
There are 9 spell levels. The mage may cast only a certain number of spells per day.
I built a tabbed pane (9 tabs) that has 9 empty squares (images) in each tab.
The numbers below (4, 3, 2, 1 and 0s) are how many spells that the mage may cast.
I want to set the squares that won´t be used unvisible.
example:
if he can cast 4 spells on level 1, image1square5 through image1square9 become invisible. 3 spells on level 2, image2square4 through image2square9 become invisible.
I tried this:
int lvl1, lvl2, lvl3, lvl4, lvl5,lvl6,lvl7,lvl8,lvl9;
lvl1 = 4 +1;
lvl2 = 3 +1;
lvl3 = 3 +1;
lvl4 = 2 +1;
lvl5 = 1 +1;
lvl6 = 0 +1;
lvl7 = 0 +1;
lvl8 = 0 +1;
lvl9 = 0 +1;
for (int i = n1; i <= 9; i++) {
image1square+i.setVisible(false);
}
for (int i = n2; i <= 9; i++) {
image2square+i.setVisible(false);
}
and so on...
How do I use a variable inside of a FOR?
使用数组或列表,而不是顺序命名变量。
如果要创建基于图块的游戏,则多维数组或List<List<?>>
会更合适。
I went back and studied, but still won´t work. Here´s what I have now:
I omitted the
jImage1Empty1, jImage1Empty2, jImage2Empty1, etc,
but they are declared. They are jlabels with an icon on it. I have 9 images showing in each pane, but after started, it should set a few to setvisible(false).
int lvl[] = new int[9];
lvl[0] = 4 +1;
lvl[1] = 3 +1;
lvl[2] = 3 +1;
lvl[3] = 2 +1;
lvl[4] = 1 +1;
lvl[5] = 0 +1;
lvl[6] = 0 +1;
lvl[7] = 0 +1;
lvl[8] = 0 +1;
String img1 = "jImage1Empty";
String img2 = "jImage2Empty";
for (int i = 0; i < 9; i++) {
img1 +lvl[0].setVisible(false);
}
for (int i = 0; i < 9; i++) {
img2 +lvl[1].setVisible(false);
}
}
I wanted the result to be like:
jImage1Empty5.setVisible(false);
jImage1Empty6.setVisible(false);
jImage1Empty7.setVisible(false);
jImage1Empty8.setVisible(false);
jImage1Empty9.setVisible(false);
jImage2Empty4.setVisible(false);
jImage2Empty5.setVisible(false);
jImage2Empty6.setVisible(false);
jImage2Empty7.setVisible(false);
jImage2Empty8.setVisible(false);
jImage2Empty9.setVisible(false);
etc...
But not as string. As a command.
Is it possible? Help
