I do not know if this fits here, but ...

I have a few small questions. I am currently working on a simple solution for flashlight lighting. I have created a simple torch-decal as a weapon and now looking for a way to activate this with the F-key. Perhaps best would be a total solution for the lighting control (F-key). Is there a way to use this animated decal as wallpaper? And is it also possible to animate the light cone image so that you can imitate the flickering? If so, you can use it for any kind of lighting, and also carry and use a one-handed weapon. I also know that decals are outdated, but would not that be useful as an interim solution?
I sincerely hope that I have expressed myself understandably and I am grateful for any constructive response.

This may give some clues
Have you mid about using particles rather than decals?
I remember someone working on that, but can remember where.

The weapon system is not the way to go because it doesn't allow enough control. Instead, you will need to write a script that parents a torch entity to the player at all times, but only draws the torch when the player presses F. In terms of lighting, the flashlight is not the way to go either, because the light from a torch would not project as a beam, but would spread out in every direction. Instead, you need to create a dynamic light that follows the player at all times but is only triggered if the player presses F (and has already picked up the torch).

I was working on something very similar earlier this year. This is as far as I got:

This version used several different scripts to control everything and was a bit messy. AmenMoses then very helpfully stepped in and rewrote most of the scripts into one control script that also fixed a decal issue I was having. We both moved on to other projects but this is as far as he got:





Hope this helps! I'm sure Amen can explain better how the system works

Ich danke euch beiden für die sehr interessanten Antworten.
Was habe ich verpasst, diese Beiträge habe ich nicht gefunden.

@3com Ich werde es ausprobieren, da es ein relativ einfacher Weg ist dies zu realisieren. Natürlich würde ich lieber partikel nehmen, aber es ist nicht alles für mich nachvollziehbar. Ein zusätzliches Problem ist, dass ich keinerlei Englischkenntnisse habe und somit auf google & co angewiesen bin. Ich bin immer bestrebt, etwas einfach zu gestalten, damit es jeder(auch ich) ohne viel Wissen benutzen kann.

@Avenging Eagle Das ist natürlich eine elegante Lösung. Ich habe auch schon versucht, ein dynamisches Licht mit mir rumzutragen, aber ich bin da kläglich gescheitert. Mir ist auch klar, dass das Waffenscript nicht die Lösung ist, aber ich weiss es eben nicht besser. Falls diese Lösung mal veröffentlicht wird, würde ich mich schon daran versuchen. Spannend könnte auch sein, dass man die Fackel mit der linken Hand trägt, um so noch eine Waffe benutzen kann. Aber das wäre vielleicht schon zuviel des Guten.

Ooh ... Just noticed, that's the way it can happen. I exchanged the text.
Sorry.

Thank you both for the very interesting answers.
What did I miss, I did not find these posts.

@ 3com I'll give it a try as it's a relatively easy way to do it. Of course, I would rather take particles, but not everything is understandable for me. An additional problem is that I have no knowledge of English and therefore rely on google & co. I always strive to make something simple so everyone (including me) can use it without much knowledge.

@Avenging Eagle This is of course an elegant solution. I also tried to carry a dynamic light with me, but I failed miserably. I also realize that the weapon script is not the solution, but I just do not know it better. If this solution is published, I would try it already. It could also be exciting that you can carry the torch with your left hand so that you can still use a weapon. But that would perhaps be too much of a good thing.

Well I assume you could simply flip the model to it's mirror image to make it left handed.

If AE has no objection I can post the last script we were working on but you would have to alter it to suit your needs, as the torch is carried close to the player you also need very good quality particle sheets like the ones AE made.

I would be very happy about it, but if AE does not want that, I can understand it too. For me it is interesting, because I will soon offer my medieval weapons, where a torch is included, for free download. I also work on a medieval dungeon with a tunnel system. Even there, such a highlight would fit quite well.

You made some nice models and used them for weaponry. That was also my intention, until it came to my mind, maybe you can do it all over the control with the F-key. The torch and the fire in my video is a single Decal, the fire animation, I just created quickly. That would have to be better then. In this way you then have a hand free for possible weapons. The easier way would be yours, of course. I have already tried it out, but .. I can not get the bullet decals and also this little picture on the bottom left. I'm too stupid to do that. Would be nice for your solution, too, if I take the lamp or whatever the light should turn on and if I remove the lamp it would go out again. For that I just lack the necessary knowledge.

I have no objection. Come to think of it, I can't remember how far you got with it so I might download it again too!

If I thought it would help, I'd provide you with my spritesheet, but it's so specialised to my own torch model (and the particulars of my game) that I don't think it would be much help.

One of the reasons I didn't use the weapon system was that I wanted to assign a particle emitter to a limb of the torch. In order to do that, you need to know the entityID of the torch, and HUD weapon models don't have entityIDs. In essence, Amen and I had to build our own weapon system where the torch entity follows the player around and moves in parallel with them at all times.

Lafette II, I used your Mystical Dark Age pack for my levels a few months back - I love it! I made a few adjustments to the textures to make your assets work better in PBR, hope you don't mind. Please do create more, your work is always top quality

I think this is the latest one, the same script does all three models, the candle the torch and the lantern but if you can figure out how it works you can adapt it.

The name if the entity drives the functionality in the script.

The weapon_onlyone2.lua is an altered version of the standard one and is attached to the static model, when you collect the static model the ignitetorch3.lua script takes over (it should be attached to the carried entity and a dynamic light).

Hi...
Although I have not tried anything, but I'm already grateful for the quick help.
@ AE Which particle generator did you use? Unfortunately, I have no modern, so the decals always look so outdated. I once looked at the rigzsoft, but I do not know, the animations look rather outdated and with the trial version you can not save anything to check. But your fire looks really realistic. As far as the Mystic models are concerned, I did it before pbr and was too lazy to convert them. That's why I have a new pack at work now. But there again I have problems with the animations and collisions. If I get the thing with the light solved, I'll deal with it intensively again. As an encore, the weapon pack is planned.
@ AmenMoses Thanks for the quick feedback. I would already be 10 percent of your programming skills enough to gain a little more understanding of the processes. I used to do some basic, tp and Delphi during a retraining. That was nice, but after 15 years there was nothing left. I admire all those who sit down there and persistently seek a solution and then find it. Also thank you very much.

That's because it is real! I made an actual torch from cotton bed sheets, string, and metal pole and then set it on fire and filmed it at 50fps in 4K resolution on my camera. I then used a combination of my editing software and Adobe After Effects to create loopable sections for use as spritesheets. Sadly this means my spritesheets are very tailored to the torch model I was using so probably would not line up for everyone.

I look forward to your new pack. I'm less interested in the traps, I just like the walls, corridors, floors, vaunted ceilings, columns, all that good stuff

@ AE Now I'm disappointed. Bed burned down due to 64 frames or so. Seriously, that's a brilliant idea. Some time ago I also had such a train of thought with water things. I wanted to create beach waves. However, I wanted to win those from a video. But I quickly rejected that. I found a good-looking animation with 36 pictures in the net, but it does not look like a torch. How many frames does your animation have? To the pack ... Soon I'll let a video of the vault pack grow over.

@ JC LEON I beg you, with my Decal I can not really win a flowerpot. I mean, I have not even used a model yet. That's just a sprite.

Nevertheless, the thought does not leave me now to win a fire in this way. The idea is really spicy ... Mmh ... Maybe I could mushroom a nuclear .....

I guessed it again. I fumble around for a while, without success, I'm probably too stupid to distribute the scripts. Could someone ever send me a complete sample object? I already understood that with the pictures, with the torch, which should be taken, too. But how is it with the light and the carried object? Is that a weapon or something? I would be grateful for any help

Do you mean the sprites? Since you make a decal of it with decal_animate8.fx

Fortunately the torch burned for several minutes so I had lots of footage to choose from. I only used 115 frames for the main loop. In my game, the torch has to gradually burn out and extinguish, so I was also looking for other parts with less flame I could use for that.

Quote: "Some time ago I also had such a train of thought with water things. I wanted to create beach waves. However, I wanted to win those from a video. But I quickly rejected that."


Water is very hard because you need to light it very carefully from behind so it shows up on a black background. At least fire stands out from black. For waves, it is much more difficult. Theoretically, if you had a drone, you could hover it over a beach and film directly downwards, capturing the white froth of the waves. Then you'd chromakey out the blue of the sea to leave behind the waves. You'd probably struggle to key out the beach as well because it would be a light colour, so you'd need to shoot this footage in Iceland or the Canary Islands where you've got black volcanic sand that might be easier to get rid of. Sounds like a lot of work! In this instance, faking it digitally would be much easier.

@Lafette II: You won't be able to simply use the scripts as they are, you will need to study them to see how they work, especially the parts about naming the entities, and adapt them to fit with your own entities/images.

Here it is.

Attach script to the torch.
Put the png file in effectbank/particles.
Put the .fx file in effectbank/reloaded.

Let me know if I've forgotten anything.

So with this script:
1) E to pick up torch, this disables the standard flashlight.
2) F to hide/show torch.
3) Shift + E to drop torch, this re-enables the standard flashlight.

The 'swapping' one torch for another is a bit flakey, I'll try to track down why that is and I really need to simplify the script a bit because it is getting a bit messy.

What the script will also require is detection of 'two handed' weapons selection or 'left handed' weapons selection (are there any?) and act appropriately, i.e. in the first case hide the torch and in the second probably switch hands.

Thank you very much for solving my problem. With the additional features I have more than I could expect. Thanks again to Avenging Eagle for providing his fire animation.
