Question by TheHardkaare · Apr 26, 2014 at 06:18 PM · game model png photo

Why can I not use .png photos as my game assets?

Hey.

I'm making a Space Shooter for my exam project in programming, and decided to get help from the official Unity tutorial on Space Shooters.

I've come into a problem very early on - when creating the main ship. It's in the very start of this video: https://www.youtube.com/watch?v=hKB0NIiWliE

I know he uses 3d models for the ship, but can't I simply use a png picture instead? It is a 2d shooter afterall.

When he drags the model into the Hiearchy window, mine just won't allow it. This is probably a fundamental error, but I do not have any idea how to fix it, since I'm very new at Unity.

well you could maybe just add a quad and apply the image onto it.. I think black will be transparent, maybe you need to find the right shader

that is actually explained in that tutorial at some point when you make the laser bolts. "particles/additive" is the shader used on the bolts.

Scrappy_ - I've now looked through that tutorial, but it seems very odd. In my game, it looks like this http://i.imgur.com/vhAQVd4.png

And in the scenes, it looks like this http://i.imgur.com/TDDgbYS.png

What am I doing wrong?

It looks like you just need to set up the camera or rotate the image to face the camera.

and did you select the particles/additive shader to get rid of that black?

In order to have transparency you need two things: 1) an import setting on the texture that save the alpha channel, and 2) a shader that supports transparency.

Select the texture. You will see the import setting for that texture on the right.
