如何在没有scene2d的情况下检测是否已触摸纹理libgdx [英] How to detect if a texture has been touched libgdx WITHOUT scene2d

问题描述

我想知道是否有无需使用scene2d就能检测到某种纹理的触摸的方法. Gdx.input.isTouched()在整个屏幕上检测到触摸，是否可以使用某种方法在没有scene2d的情况下检测出纹理上的触摸?

I want to know if there is a away to detect a touch on a certain texture without using scene2d. The Gdx.input.isTouched() detects a touch on the WHOLE screen, is there a way i could use something that detects a touch on a texture without scene2d?

推荐答案

当然有，我也从不使用screne2d.

Of course there is, I also never use screne2d.

使用您的更新方法

  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
     }
}
