So I am making an FPS and am wondering how to do the following, I am using the realistic FPS prefab from the asset store.
-Care Packages with guns and such
-Vehicles, would be a nice addition but not entirely necessary
-Multi-player using the free Photon on the asset store
Ooooh and yeah I don’t know how to code, so this should be interesting. I will update this list as we go.
Yeah… For everyone I’ve ever discussed this with, they all say start with something small for your first project, rather than something too large that you can’t chew which you’ll leave in the middle of it. I second this opinion. I’m even doing a “simple” game right now and this is taking much more time than I expected to make it all from scratch.
I’d suggest to follow Unity tutorials (particularly FPS video tutorials), because you’d learn the basics alongside working towards your goal. Once you get some basic stuff down (try to make a simple level, then get them slowly more complicated while adding features one at a time), then try more and more stuff, such as vehicles.
I can tell you now, many of those things need quite a bit of varied experience. Multiplayer - if it’s not over the same computer or such - will take networking skills and maybe even a server.
Also, if you’re doing this by yourself, you’ll have a lot to learn. Take notice that there are free 3D models and textures online- took me a while to figure that out. It would have saved me a lot of time, although I’m sort of happy I know how to make some basic stuff myself 
I realize most of this, I already (Almost anyway) have the base for everything. I find that was the advantage of using the realistic FPS prefab and terrain is easy enough. I try to watch all of the tutorials that I can already also. I am in no, way, shape, or form calling my self experienced, just that I have a little something to make better. And I intend to do it!!! Thank you for the response though, first one!
I am not going to tell you to start small or any thing like that, I’ll just give it to you straight.
What your attempting is big, but what the hell, right?
Guns, first you need to create the model in a 3D program such as Maya or Blender.
1.2) From there, Brackeys has a great tutorial and script on how to setup the gun using their already created script. Once you learn JavaScript better and know how to use Unity you should then move on to creating your own scripts. (Search brackeys in youtube search)
1.3) Care packages are just a matter of a model of a box with a GUI attached to it that is called when a key is pressed down. Then from there removing the GameObject from the scene.
Vehicles can be tricky to create when going Online. Try SP first.
Go SP first, then work your way to MP.
The simplest way to make a Day / Night cycle is to make an animation on a directional light that rotates it in a loop.
Menu with objects is simply done by drawing a GUI and creating Functions.
A chat bar would be for MP, and of course start of SP.
I know you don’t want to hear “Start small” and that bull shit but it is the truth. You don’t need to go as low as remaking Zerg, but try something less advanced. Also even when making a big project if your not familiar with how networking goes, don’t attempt it right off the bat. As it is more than a complicated process.
If you need any help achieving any of the tips I gave you, feel free to reply or add me on skype ( kriller509 )
