我有一个程序,一个人可以在屏幕上放置一个代表扭曲门的元素。我想知道之后如何找到元素的位置,以便程序可以捕获该区域的点击。
这是我目前拥有的:
int xCoord22[];
int yCoord22[];
int numSquare22;
int warpGate = 0;
public void init()
{
warpgate = getImage(getDocumentBase(),"image/warpgate.png");
xCoord22 = new int[100];
yCoord22 = new int[100];
numSquare22 = 0;
}
public void paint(Graphics g)
{
warpGate(g);
}
public void warpGate(Graphics g)
{
//Checks if warpgate == 1 then will make the warp gate where the user chooses
if(warpGate == 1)
{
g.drawImage(warpgate,510,820,100,100,this);
//Use the custom cursor
setCursor(cursor2);
}
//Building the pylons
if(Minerals >= 150)
{
for (int k = 0; k < numSquare22; k++)
{
g.drawImage(warpgate,xCoord22[k],yCoord22[k],120,120,this);
//Makes cursor normal.
setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
}
}
}
public boolean mouseDown(Event e, int x, int y)
{
if(warpGate == 1)
{
if(Minerals >= 150)
{
xCoord22[numSquare22] = x;
yCoord22[numSquare22] = y;
numSquare22++;
handleWarpGatePlacement();
repaint();
}
}
//Checks to see if the person clicks on the warpGate icon so you can build it
if(x > 1123 && x < 1175 && y > 782 && y < 826 && onNexus == 1 && Minerals >= 250)
{
warpGate = 1;
}
所以,基本上,当你点击时,x > 1123 && x < 1175 && y > 782 && y < 826
你可以放置一个传送门。我怎样才能做到这一点,以便您以后将它放在任何地方,您只需单击它,它就会像一个system.out.print("hey");
或其他东西一样?
