Quote: "1. How do I make the lights flicker?"
What you need to know is that this effect does not work properly with shader intensive visuals. That means that if you use shaders on your walls (for example) the light will not flicker.
This is how you do it: you place a light and make it dynamic. (just press "y" or adjust it in its properities) and then you select "light2.fpi" as the mainscript. (or you type in "light2.fpi).
I just so happen to have an
example video right here
Quote: "2. When the player enters the room, how would I trigger certain objects to move?"
There used to be an awesome fpsc game named "daemon" by sYn. I remember it having some wicked poltergeist stuff going on but I do not know how to do this.
However if you got to the folder you installed fpscreator in. There is one called docs. Inside you will find the official community guide. (ocfpscguide). Open it and go to page 135.
There is a tutorial for this! (who says fpsc has no complete documentation?

)
Quote: "3. With the mirror effect (and as far as posting pictures on the walls), how would I go about doing that?"
Pictures for the walls are just models. So you would have to look up the entire getting models into fpsc thingie for that. (also in the community guide).
There is however also some neat software called "signs" for fpsc (at least there was back when I used it) which makes them with just a few clicks.
As for mirrors: you can have realtime reflections on the floor using the water shader but not on a wall. Sorry. You can fake a reflection by having a screenshot on your room as a cube or specular map but I advise against that. Players respond unwell to this.
Quote: "4. I'd love to have writing in blood on the walls as well as journal entries for the player to find. Any ideas on how to do that?"
The blood on walls and the writing...Use overlays (thats the easiest for newbies and more convenient than baking it on the segment textures). Make sure that your overlays are immobile and dynamic. This is important!
There should be an entry on how to make them in the guide. If not: its a planar mesh with a texture on it.
Journal entries to find: You can just have a picture show up via script. There is a tutorial on page 77 of your guide
Alternatively you can buy
this pack.

Don't worry! You are already taking the right steps by asking first. The true noobs are outside of this board, spamming youtube and indiedb with awful games
I wish you the best luck with your development! Even though we are overfed with horrorgames, you seem to have a more interesting angle than "amnesia clone" or "slender clone" or "OMGz! Zombieees!"
Keep in mind that there is far more possible with FPSC than it may seem and remember to ask whenever you encounter any problems.
