This was like a 3D version of an old 80s RPG Horror game. It also played like a Minivania. Very nicely done. I'm really curious what shader you used for everything. It was a very cool effect!
My only complaint was no controller support. Playing with a keyboard hurts my hand.
Really strong entry overall.
Hey! Here's the shader I used as a starting point: https://github.com/tufourn/Dither3D-Godot
I then modified this for the invisible objects by adding something like this:
void fragment
{
ALBEDO = [call function from Dither3D]
ALPHA = get_alpha_from_spotlight(world_pos)
}(where I got the world_pos using one of the methods from here)
My get_alpha_from_spotlight() function would be passed the position, angle, brightness etc of the most recent light that the camera had created (each time you take a picture, it just moves a spotlight to the player's position). It can then test for whether the vector (world_pos - spotlight_pos) is within the cone that the spotlight lights up, just using maths (testing against cos(spotlight_angle) etc, and using smoothsteps to make it look okay).
I had depth ordering issues, so I placed all the invisible objects on a higher render priority, so they always render first (which is a massive bodge, but it sortof held together for the room layouts I used).
I hope that makes sense, if you'd like any other details let me know and I can share my code / explain other bits.
As for controller support, I'm sorry I didn't add it in. I really should've, as it wouldn't have taken very long at all compared to other features. I'll add it to my template player controller script so I can use it for next time, thanks for pointing it out!
Thanks for playing :)
Thanks for all the info!
If it helps, take a look at my Controller Plugin and Camera 3D Plugin. I use them together with my Character 3D Plugin to support mouse/keyboard and controller out of the box. Along with providing an image for every key/button for use in your UI that tracks the last thing the player used as a controller. (You can see that last part in my current game if you open the Controls window in the upper right of the HUD.) They support multiple camera angles including first person, third person follow, Isometric, birds-eye view, etc. Allowing the player to scroll through them. Feel free to use the plugins or grab the code that helps your implementation.
The main difference between the two is when you're using a mouse you have to reset the look variable every frame, and with the gamepad you have to let the value accumulate.
