libgdx - 如何在没有scene2d的情况下检测纹理是否已被触摸libgdx

Question

我想知道是否可以在不使用scene2d的情况下检测某个纹理上的触摸。 Gdx.input.isTouched() 检测到整个屏幕上的触摸，有没有办法可以使用某种方法来检测没有scene2d 的纹理上的触摸？

Answer 1

当然有，我也从不使用 scene2d。

在您的更新方法中

  if(Gdx.input.isTouched())
{
  Vector3 tmp=new Vector3(Gdx.input.getX(),Gdx.input.getY();
  camera.unproject(tmp);
  Rectangle textureBounds=new Rectangle(textureX,textureY,textureWidth,textureHeight);
  // texture x is the x position of the texture
  // texture y is the y position of the texture
  // texturewidth is the width of the texture (you can get it with texture.getWidth() or textureRegion.getRegionWidth() if you have a texture region
   // textureheight is the height of the texture (you can get it with texture.getHeight() or textureRegion.getRegionhHeight() if you have a texture region
  if(textureBounds.contains(tmp.x,tmp.y))
     {
     // you are touching your texture
     }
}
