两个LPDIRECT3DTEXTURE9的每像素碰撞？(Per Pixel Collision for two LPDIRECT3DTEXTURE9?)

两个LPDIRECT3DTEXTURE9的每像素碰撞？(Per Pixel Collision for two LPDIRECT3DTEXTURE9?)

我搜索过但没有发现任何与C ++代码和DX LPDIRECT3DTEXTURE9 ，我能找到的是其他引擎的每像素冲突，我需要原生的东西，现在我有一个边界框碰撞，按预期工作，但你知道当碰撞发生在两个alpha像素之间时，它也会将其报告为true，因此我需要增强它并按像素进行渲染。

所以目前我有两个Rects和两个LPDIRECT3DTEXTURE9 ，有了intersectRect函数我可以知道是否有碰撞，那么我需要进一步处理lockRect和pbits，但似乎我无法弄明白。

谢谢

I have searched and haven't found anything related to C++ code and DX LPDIRECT3DTEXTURE9, all i can find is per pixel collisions for other engines, i need something native , now i have a bounding box collisions which works as expected, but as you know when the collision happens between two alpha pixels it will also report it as true, so i need to enhance it and make it per pixel.

So currently i have two Rects and two LPDIRECT3DTEXTURE9, with intersectRect function i can know if there is a collision, then i need go further by dealing with lockRect and pbits but seems i cannot figure it out.

Thanks

最满意答案

没关系，我解决它，它与我描述的方式相同，锁定并循环在pbits上。

Never mind, i solve it, its the same way i described, lockrect and loop over pbits.
