Flashlight

Version 1.2 (Minor flash issue fixed)

Explaination

Ever want to add a flashlight to a dark/scary game? I think a lot of people have, and I stumbled upon a good way to do it. It's not perfect like a real-time shadow system, but it's simple and easy it use and integrate into any 3D games that are dark with excellent speed and little code.

Is it simple and basic? Yes. Does it get the job done? More-so than anything else I have seen.

How-to

The example is commented and easy to understand. Heck, I bet a novice user could figure it out.

As the game info explains, it doesn't fit into every game. Games that have large areas or have brightly colored textures (The ones in the example are kinda pushing it >.>) does look as good as they would with dark textures more hallway areas.

To fit this into your game, copy the obj_flashlight, spr_flash, and spr_dark into your game. The in-editable comments explain how you can change some of these to make the flashlight fit into your game more fluently.

The flashlight will show the way!

Give it a shot and tell me how I did! Please post with your comments and suggestions on possible improvements.

thats a realy good example, but you should use a different sprite, like this one i just made

Well, It's easy to change what sprite you need, so I just made a really simple one for display purposes. You can technically use a batman or hello kitty shaped one(as I believe some cheat codes allowed you to do in Doom3), and color it with the other sprite.

In the game I'm using this in, I have a sprite that makes the flashlight seem old and dirty, due to some of the grays I put into the black area.

I'm glad you liked it, and thanks for the comments.

That's awesome, I could really see this being used in a dark game (like you said). It's probably just because the level you used was kind of claustrophobic, but just to let you know, it kind of strained my eyes, but it's hardly an issue at all.

Incredible work, simple beats complicated!

[Joysurrender]

Wow! Great!

[ga05as]

its great but i think it looks better with this images as the torch

Working from a photo of a real flashlight/torch really raises the creepiness.

has anyone noticed that for a split second while turning off the torch, the screen is suddenly light?

[Dragonos]

Yes, I noticed too it is due to poor programing and is easily fixed.
7/10 for the idea, but needs ray-tracing. Then I'll be impressed.
Great for GM though Keep Expanding!

It's been a while, but i think I remember that happening. I'll fix it if I get time. It has to do with the fog turning off before the picture is drawn, so it can be fixed in a second.

EDIT:Yeah, it was the that fog was in the draw event, and didn't take effect at the correct time, also having it switch on and off in the "F Press" event will actually save time as it won't be reset each step. I'll put up v1.2 up now.

Yeah. The image included was a really basic version. I tried yours and it's pretty nice.

Right. The pros have problems with that.

That's for the comments everyone. I'm glad to hear you're enjoying this well enough.

The example works well enough if you dont plan on using any other lights in the game. Due to the overlay it causes the other lights to become darker in the area not "lit" up by the overlay.
For what its worth, 5/10

Okay. I didn't know how this would look with other lights, so I guess this answers my question.

Thanks for the comments.

hmmm... practically, you could hardly sell this as a flashlight, not even for a FPS (in 3rd person this wouldn't work at all). The problem is that light beams stretch along surfaces if they hit them at an angle, which makes this one look really fake... sorry

This is kinda based on you eyes being right at the flashlight so you wouldn't see that happening (which legitimately you wouldn't have unless you had a facelight...) but it's still better than anything else I've ever seen. :\ If you can show me an alternative that doesn't lag below 10fps... I'll eat my sandwich...

[briantrlov]

simple, but i do want to add a: a flashlight would really boost the effect and a light trace from the flashlight to the circle besides that its creative and useful...

EDIT: ok since i thought it looked horrid as a light alone i added a picture of a quick 3d flashlight i created and put it in the game heres a screenshot if you want i can message you or just post the link to the game but i don't want to post it without your permission.

with your permission; here is the link to the game i implemented the flashlight in but hence the fact the light will get bright once the flashlight is turned on and idk how to make it always dark or light depending on preferences, anyways here it is: Download

[antome]

this is really, really cool!

Just wondering though, how easy would it be to allow colours to work for the flashlight? So that I can turn it into a visor .
I don't mind if it has to stay black, but it'd just help in the long run..

Oh goodness, don't tell me you're just drawing a sprite over the screen.

That's just what it does. Simple, but effective.

You could have checked it yourself, and you'd have seen..
