Day/Night and Onscreen Clock! Plus Clear Lights

[Star]

This is me taking a screenshot of my game and putting it in a paint program and making my own lights using another layer

This is me having lights appear at night in my game. As you can see the lights go over top of the dark layer and don't actually clear it up. I wanna able to open up the dark layer.

Any ideas on how I could go about working around this?

 

[Brewmeister]

Ummmm, instead of adding white, subtract black.
Your base is a "daylight" map. The overlay is mostly black (semi-transparent). The areas with the lights are more transparent.

Lemme see if I can find an example...

[Star]

So you're saying I should create a overlaying picture for it that has all the light shades and stuff. Well, that would work if everything was the same thing, but I'm doing a DNS so 24 hour light duty. Can you imagine making lighted maps for all 12 of 24 hours on 100x100 maps O_O. People will scream at me for file size.

Let me explain this a little better.

I'm using a fog that's just a dark transparent overlay of the map, Pretty much would work the same as change screen color tone in the event page.

But I want a way to make an animation that cuts through either the tone or the fog making it appear to be a light source.

Is there a way to do that? Or am I screwed into making lots of picture files?

 

[Glitchfinder]

The problem with having a light system that dynamic is that the only way to do it properly is to do it in a 3D game. Any time you do it in a 2D game, you either have to have no dynamic light system, a few set times of day (a la Pokemon Gold, Silver, and Crystal) or a fuckton of images to represent every possible time of day, which just isn't an option.

 

[Brewmeister]

I was merely suggesting a strategy. Adding white at any transparency will make it look 'foggy' / 'hazy'.
What if you placed your animations first, then filled in the rest of the fog overlay with a single 'fill' color?
As long as you know where the animations are, we could write a 'Fill' script to lay in a single color wherever the animations 'aren't'.
You'd just need to match the edges of your animations to the fill color.

 

[Star]

Thanks for your help guys. You've been a ton of help. I see that. I know your first strategy, brew, would be the wisest. If I had smaller maps itd be easy to work with and I can move shadows during the suns motions. But since that would require lots of effort and time and a ton of images I'll try your second suggestion for now. I had thought of that in my head and I did think of filling the places where animations didn't go. But I was gonna do it in lots of events which would be horrible for my size map. I'm willing to try scripting this out. I hadn't really thought of it. I'm still very low level at scripting. I made my own cms once and edited a lot of things and still try. If you can help me figure how to do this it would be great. I know the class would be scene_map but how would I make a fill "unless animation present"?

 

[Brewmeister]

I was playing around with this a little bit. It's not as easy as you'd think!!!
I think the best solution would be to add functionality to the fog layer itself, and use 'subtraction' images to do the animation.
i.e. your light image would be black in the center, at the light source, then fade to white around the edges.
Then when subtracted from the fog, whatever color/tone, it would produce a nice realistic light effect.

The other problem would be moving lights. Flashlight, torch, etc.. I noticed you had a light on the player above.
Maybe this is just a matter of having another subtraction object on the fog layer, and synchronizing it with the player.

Did you look at any of the other Dynamic Light scripts that are already available?
Do that first, and see if anything will suit. Maybe we can make some tweaks from there.

Okay, I gave it a shot, but I have trouble refreshing the thing during the time change. It gives me an undef variable when I do $Nightime.refresh I'm not sure I'm doing it right, infact, i know I'm not. Plus, I haven't got it to span over the map yet.. Argh, this is hard.

Of course, we'll need a way to control the size. Probably just extract it from the map size.
(If we weren't adding lights, we could just use a Plane object instead of a Sprite.)

Then we can take a look at how to implement the lights.

[edit] got the map size..

 

[Star]

Hmm.. Now that I think about it. If I can get this to work from the map and paste a 32 x 32 Square on every tile according to the map size. I can tell it not to paste a tile if a tile has a terrain tag of a certain number so i can place lights. Since there will be no moving lights. I can only seem to get it to paste a 32x32 on the screen itself that scrolls with it instead of staying put.

I do like how you edited and made it much more simpler, I learn something everyday, and I like how the update thing was soo easy yet I couldn't figure it out. "Case" seems much more helpful than pasting a crap load of "IF MY SWORD IS YELLOW TWO"

I know if I can get this to work as a fourth layer of the map I can use an array (is that what it's called?) the "for i in blah blah blah. Which I'll use for i in ...$game_map.width and for j in ...$game_map.height then x = i * 32 y = j * 32

 

[Brewmeister]

Ah, I didn't check to see if it moved when the screen scrolled...
We just need to adjust the sprites position when the map moves. (just like the @tilemap.ox/oy & @fog.ox/oy)
Now you can use a full map width/height sprite instead of a bunch of 32x32 images.

 

    # Update nighttime sprite

    @nighttime.ox = $game_map.display_x / 4

    @nighttime.oy = $game_map.display_y / 4

    if @hour != $game_variables[9]

      @nighttime.refresh

    end

 

If you won't have any moving lights that makes it easier. My thought was just to SUBTRACT the pattern for a light from the nighttime bitmap, leaving a hole of transparency that let the 'daytime' underlying map show through. I'll see if I can make this work.

[EDIT]

Check this out...

http://www.hbgames.org/user_files/Star_ ... g_Test.exe

hit the mailbox to change the hour. You can still lay animations under the 'light hole'

If this works out, we just need to figure out how to place the lights per each map, and how to control the size of each light.
And how to turn the whole thing off on maps where it's not needed.

What you think?

 

[RadethDart]

Eh, did you check to make sure you are disposing the scene when you go to the menu? It also makes the game really laggy if you cause a ton of hours to go by. :D

 

[Brewmeister]

The scene gets disposed, but I didn't dispose the 'nighttime' sprite. Easy to add.

I'm not getting any lag, and I'm also unfolding a big piece of sheet-metal on my laptop (big CAE calculation that's been running for the last 15 minutes...)

refresh only gets called when the game_variable changes (once per game hour), so although the subtraction algorithm is a bit of a hog, it only operates on a relatively small area at a time, so it shouldn't have much impact.

This is a RAD-JAD WIP, so it's nowhere near 'done'. :scruff:


Star, add this to Spriteset_Map

  alias dns_dispose dispose

  def dispose

    dns_dispose

    @nighttime.dispose

  end

 

 

[Star]

Beautiful.. This is beautiful. *tears in eyes* Amazingly fine work. Incredible.

Oh add this too

if @hour != $game_variables[9]
@nighttime.refresh
@hour = $game_variables[9]
end

Else it refreshes forever until your computer implodes. Which is what Radethdart was talking about.

Now to figure out how to comment lights as events on the map. That way you can have several maps with light locations. It seems we're moving along nicely and I feel like I haven't done crap, but I sure am learning a crap load.

"Moving lights?"
Nah, Too much for me. Would be sweet to have a guard or two walking around with a torch like in obilivion but lets take this one easy step at a time.

I know I've seen Scripts and script makers use event "Comment" as a way to do things so I'm going to see what they did and see if I can't replicate it.

 

[RadethDart]

I know I am not helping at all, but I am enjoying the progress on this script, and I like what you are doing with it, and how far you have gone. It would really come in handy.

 

[Brewmeister]

I can't believe I left that out. I also can't believe I didn't notice the lag from it. This quad-core i7 & 8gb of Ram hammered right through it.

I like the idea of using events. One thing to keep in mind is I used an event for the fire light, and we'll want the light effect centered on the same event. My first thought was to use event.name since it's easier to access than a comment buried on a page.
But, the information we'll need to input would be the location if different than the center of the tile, and the diameter of the light effect (or which light effect picture to use)
I think pictures is better, that way if you, or anyone else wants to use it in a corner or to more accurately show the effect on a wall (bend line at the floor), they can make the subtraction picture any way they want.

This is a learning experience for me too. And it's something that's going to be pretty useful, so it's fun.
I'll let you see what you can come up with on the comment.

Radeth, it's all good! another set of eyes never hurts.

Be Well

Okay, I tried taking something from SDK. I'm not claiming it, they'll get credit of course. But it's not working. Throws head on spear.

I tried making it to where it sorts through all events that have Light as Comment and see if it can give me that event number and I'll be able to use that to find the x and y of them. Blast. Maybe you have an idea? I might have to keep trying at it later.

So brew, I was thinking about this. I really like the idea. I was thinking it would be a good idea to do something more of a block transfer for the image. You of course would have a list of other lights in the area, and would be able to determine their spread.. so you do a block transfer for what you can, then do your method to determine the difference of the remaining overlay if lights are too close. I will try to put together some mock code here in a bit.. but I am gonna eat some dinner first. Just thought I would mention it incase you are out there looking at this now.

 

[Brewmeister]

Gubid, thanks for taking a look

I thought about blt, but I'm not sure if you can do a subtract other than the way I did it.
I kind of expected that under the hood, a blt replaced bits anyways (but in core, not interpreted, so faster).
I'd like to see what you come up with. I think I have a few other Bitmap extensions that would be cool to bundle up into a package.

Star, the first argument needs to be a list of commands from a page, try...

SDK.event_comment_input($game_map.events.pages[0].list, 1, "Light")

The 1 might need to be a 0, I'll plug this in & give it a try tomorrow. (Couch time with mumma :scruff: )

Since this has become a scripting project, I'm sliding it over to Script Support...

Be Well

 

[Gubid]

Well, I didnt have time to get into the blt section of things but I did make some improvements to the code. I will get the blt transfer stuff when I get up in the morning. if my wife was calling every 20 secs to get to bed.. then I would do it now.. Here is the latest code.
