Java & Slick 遊戲開發(9)-Getting Mouse Input from the User

1.首先 import org.lwjgl.input.Mouse;


2 把字符串成為變量   public String mouse = "No input yet!";


在Menu.class的update function:(當有事要變動時，會執行這個function)

public void update(GameContainer gc,StateBasedGame sbg, int delta) throws SlickException

{

int xpos = Mouse.getX();

int ypos = Mouse.getY();

mouse = "Mouse position x: " + xpos + " y: " + ypos; 

}

Mouse.getX(); --> 獲取畫面的x軸

Mouse.getY(); --> 獲取畫面的y軸

mouse = "Mouse position x: " + xpos + " y: " + ypos; --> 更新mouse內容和印出X同Y軸

*請注意，這個Library的x軸同Y軸是在左下角!但在Render裏的是用Java的library,所以x軸同Y軸是在左上角

全部的代碼:

package javagame;

import org.lwjgl.input.Mouse;

import org.newdawn.slick.*;

import org.newdawn.slick.state.*;

public class Menu extends BasicGameState

{

public String mouse = "No input yet!";

public Menu(int State)

{

}

public void init(GameContainer gc,StateBasedGame sbg) throws SlickException

{

}

public void render(GameContainer gc,StateBasedGame sbg, Graphics g) throws SlickException

{

g.drawString(mouse, 50, 50);

g.drawRect(50, 100, 60, 120); //x,y,width,height

Image pic = new Image("res/logo2.png");

g.drawImage(pic, 200, 130);

}

public void update(GameContainer gc,StateBasedGame sbg, int delta) throws SlickException

{

int xpos = Mouse.getX();

int ypos = Mouse.getY();

mouse = "Mouse position x: " + xpos + " y: " + ypos;

}

public int getID()

{

return 0;

}

}
