我正在尝试进行鼠标选择,并且我单击的图块会更改为对面的图块,即。将草变为泥土,但每个草砖都有相同的“ID”,因此屏幕上的每个草砖都会变为泥土。我怎样才能以更好的方式生成这些图块?我希望它是随机生成的,而不是从像 000001100 这样的数组映射中绘制的。
块类
public class Block {
public enum BlockType {
Dirt,
Grass,
Selection
}
BlockType Type;
Vector2f Position;
Image texture;
boolean breakable;
public Block(BlockType Type, Vector2f Position, Image texture, boolean breakable) {
this.Type = Type;
this.Position = Position;
this.texture = texture;
this.breakable = breakable;
}
public BlockType getType() {
return Type;
}
public void setType(BlockType value) {
Type = value;
}
public Vector2f getPosition() {
return Position;
}
public void setPosition(Vector2f value) {
Position = value;
}
public Image gettexture() {
return texture;
}
public void settexture(Image value) {
texture = value;
}
public boolean getbreakable() {
return breakable;
}
public void setbreakable(boolean value) {
breakable = value;
}
}
瓦片生成类
public class TileGen {
Block block;
public Block[] tiles = new Block[2];
public int width, height;
public int[][] index;
boolean selected;
int mouseX, mouseY;
int tileX, tileY;
Image dirt, grass, selection;
SpriteSheet tileSheet;
public void init() throws SlickException {
tileSheet = new SpriteSheet("assets/tiles/tileSheet.png", 64, 64);
grass = tileSheet.getSprite(0,0);
dirt = tileSheet.getSprite(1,0);
selection = tileSheet.getSprite(2,0);
tiles[0] = new Block(BlockType.Grass, new Vector2f(tileX,tileY), grass, true);
tiles[1] = new Block(BlockType.Dirt, new Vector2f(tileX,tileY), dirt, true);
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();
tileX = mouseX / width;
tileY = mouseY / height;
if(input.isMouseButtonDown(Input.MOUSE_LEFT_BUTTON)) {
selected = true;
}
else{
selected = false;
}
System.out.println(tiles[index[tileX][tileY]]);
}
public void render() {
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
tiles[index[x][y]].texture.draw(x * 64, y *64);
if(IsMouseInsideTile(x, y))
selection.draw(x * 64, y * 64);
if(selected && tiles[index[x][y]].breakable) {
if(tiles[index[tileX][tileY]].Type == BlockType.Grass)
tiles[index[tileX][tileY]].texture = dirt;
}
}
}
}
public boolean IsMouseInsideTile(int x, int y)
{
return (mouseX >= x * 64 && mouseX <= (x + 1) * 64 &&
mouseY >= y * 64 && mouseY <= (y + 1) * 64);
}
我正在使用 slick2d 库。我不确定 ID 是否是正确的词,但我希望你能理解我想问的问题。
