我目前正在使用Java LWJGL制作一款3D第一人称射击游戏。我想把一个子弹朝着世界上指定的点旋转和移动。我成功让子弹在Y轴上旋转,但无法在X轴和Z轴上旋转。我如何让子弹在Z轴和X轴上旋转,然后朝着指定点移动?
以下是我的子弹类代码:
以下是我的子弹类代码:
package entities;
import org.lwjgl.util.vector.Vector3f;
import models.TexturedModel;
import renderEngine.DisplayManager;
import toolbox.MousePicker;
public class Bullet extends Entity{
private static Vector3f currentRay = new Vector3f();
private static final float RAY_RANGE = 600;
public static boolean reset = true;
public Bullet(TexturedModel model, Vector3f position, float rotX, float rotY, float rotZ, float scale) {
super(model, position, rotX, rotY, rotZ, scale);
}
public void move(Bullet b){
float distance = 2 * DisplayManager.getFrameTimeSeconds();
currentRay = MousePicker.calculateMouseRay();
Vector3f endPoint = MousePicker.getPointOnRay(currentRay, 10000);
//I want my Bullet to move towards the Vector3f endPoint
float zDistance = endPoint.z - this.getPosition().z;
float xDistance = endPoint.x - this.getPosition().x;
double angleToTurn = Math.toDegrees(Math.atan2(xDistance, zDistance));
this.setRotY((float)angleToTurn);
float dx = (float) (distance * Math.sin(Math.toRadians(super.getRotY())));
float dz = (float) (distance * Math.cos(Math.toRadians(super.getRotY())));
super.increasePosition(dx, 0, dz);
}
}
