我正在开发纸牌游戏,目前有一个很好的基础,但是当我在eclipse中运行它时遇到了一个错误.我也使用光滑的2d.

这是控制台的错误.

线程"main"中的异常java.lang.RuntimeException:当前线程中找不到OpenGL上下文.在在org.lwjgl.opengl.GL11.glGetError(GL11.java:1277)在org.newdawn.slick.opengl.renderer.ImmediateModeOGLRenderer.glGetError(ImmediateModeOGLRenderer org.lwjgl.opengl.GLContext.getCapabilities(GLContext.java:124)的.java:387)在org.newdawn.slick.opengl.InternalTextureLoader.getTexture(InternalTextureLoader.java:337)在org.newdawn.slick.opengl.InternalTextureLoader.getTexture(InternalTextureLoader.java:275)在org.newdawn.slick.图像.(Image.java:270)在org.newdawn.slick.Image.(Image.java:244)在org.newdawn.slick.Image.(Image.java:232)在org.newdawn.slick.Image. (Image.java:198)在Cards.Card.(Card.java:18)

代码我相信发生错误的来源(卡类)

package Cards;
import org.newdawn.slick.Image;
import org.newdawn.slick.SlickException;
public class Card
{
    final int numCards = 52;
    Image[] card = new Image [numCards];
    Card (int c)
    {
        String fileLocation = new String ();
        for (int i = 1 ; i <= 52 ; i++)
        {
            fileLocation = "res/cards/" + i + ".png";
            try 
            {

                card [i] = new Image (fileLocation); //line
            }
            catch (SlickException e)
            {
                e.printStackTrace ();
            }
        }
    }
    public Image getImage (int cardlocation) …
