我有一个玩家类,它是x,y位置是用xPos和yPos操纵的,我想创建一个跟随玩家的相机。
到目前为止,我已经尝试过这个:
相机类:
import org.newdawn.slick.GameContainer;
public class Camera {
public int offsetMaxX;
public int offsetMaxY;
public int offsetMinX;
public int offsetMinY;
public int camX;
public int camY;
private Player player;
public Camera(Player p) {
//Setting offset max's and minimums
offsetMaxX = 0;
offsetMaxY = 0;
offsetMinX = 0;
offsetMinY = 0;
player = p;
}
public void update(GameContainer gc) {
camX = player.xPos - (gc.getWidth() / 2);
camY = player.yPos - (gc.getHeight() / 2);
}
}
我的主要课程中的渲染功能是:
@Override
public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException {
//Translate to camera X and Y
g.translate(-camera.camX, -camera.camY);
//Scaling map
g.scale(3, 3);
//Rendering map
try {
mapRender.render();
} catch (SlickException e1) {
e1.printStackTrace();
}
//Draw player
player1.drawPlayer(g);
}
这样可行,但相机移动速度比播放器慢。我怎么能修复这段代码,还是有更好的方法呢?
答案 0 :(得分:0)
g.translate(.5, .5);
因此,在定位相机时,我必须这样做
camX = ((player.xPos * 1.5f)) - (gc.getWidth() / 2);
camY = (player.yPos * 1.5f) - (gc.getHeight() / 2);
