I am using the slick2d library. I want to know how to get the exact tile location so when I click on a tile it only changes that tile and not every tile on the screen.
My tile generation class
public Image[] tiles = new Image[3];
public int width, height;
public int[][] index;
public Image grass, dirt, selection;
boolean selected;
int mouseX, mouseY;
public void init() throws SlickException {
grass = new Image("assets/tiles/grass.png");
dirt = new Image("assets/tiles/dirt.png");
selection = new Image("assets/tiles/selection.png");
tiles[0] = grass;
tiles[1] = dirt;
width = 50;
height = 50;
index = new int[width][height];
Random rand = new Random();
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
index[x][y] = rand.nextInt(2);
}
}
}
public void update(GameContainer gc) {
Input input = gc.getInput();
mouseX = input.getMouseX();
mouseY = input.getMouseY();
if(input.isMouseButtonDown(Input.MOUSE_LEFT_BUTTON)) {
selected = true;
}
else{
selected = false;
}
}
public void render() {
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
tiles[index[x][y]].draw(x * 64, y *64);
if(IsMouseInsideTile(x, y))
selection.draw(x * 64, y * 64);
}
}
}
public boolean IsMouseInsideTile(int x, int y)
{
return (mouseX >= x * 64 && mouseX <= (x + 1) * 64 &&
mouseY >= y * 64 && mouseY <= (y + 1) * 64);
}
I have tried a couple different ways to change the tile I am clicking on, but I don't understand how to do it.
