Unity a simple way to implement a bullet

Prior to knowing that a method is more complex is to take out the map, similar to the top to bottom from left to right to traverse a graph, to remove pixels to change the pixel point. Today in the election of the Big Brother to see the following method, feel very simple, the principle should be the same bar.

Create a new script to copy the code from the link above, remember to change the name. Hang the script on top of the scene's main camera:

In the scene of a random object component remember mesh Collider convex do not tick ps:unity province point convex explanation:

(The convex didn't know much about efficiency or anything.) https://www.zhihu.com/question/40575282)

Next, notice whether the settings for this map are writable:

Set up the apply. Run the game and you're done:

Only the grass sheep look and draw a grass sheep. After you close the game, you can also see that the decal file changed:

Above.

It's okay. There are many good things to do in the official documentation.

can also be changed to try to try what effect-

Color[] C = Tex. Getpixels (0055); Tex. SetPixels ((int) pixeluv.x, (int) PIXELUV.Y,5,5, C);

Source above the link on it, because not particularly many at the end of a copy, hand lazy direct stick:
