[SOLVED] Arrow to aim

[CastorHolyday]

Hi, I'm willing to make something similar to the image above, focus on the arrow is that something that should be done using the GUI (NGUI), if so what do you advice me to do or start with, I'm new to NGUI, so I was wondering if it has something to do with 3D-NGUI, or ? because I want the arrow to be like if it was under the character, so if it's pointing to the top it should be "under" the legs of the character not over him.

Any suggestiong ? or pseudo logic ?

It's easier to actually make that with your own system than with NGUI I think.

Notice that it follows the ground, so you need a texture that either has its quad follow the ground, or do a projection onto the ground (if you want it to follow geometry). You can do this with unity:

Yeah it should be done by projecting a texture, not using NGUI.
