help with gui texture on tagged targets

i am trying to get a gui texture be placed on any enemy tagged objects in the camera field of view, i have looked on youtube and this forum but cant seem to find a simple help tutorial and most seem to be in javascript and not c#, i dont need a full targeting system only a simple way to add the gui texture to any enemy tagged with enemy tag.

thanks in advance

 

anybody?

 

if you're new to UI stuff and/or not particularly attached to the old legacy UI system (which uses GUI texture) it might be better to look into the new canvas based UI.

without knowing anything about your project it should "just" be a case of putting a sprite onto a (most likely world space) canvas

 

Cheers, bit confusing as i kept watching how to use the guitexture but now the ui has changed it seems harder to get to grips with, i take it the sprite is the ui image as i am using 3d and seems like sprite is for 2d canvas is that right
