Making a Flashlight item that uses Batteries [Demo included]

Hi! This is my first tutorial so I may not be able to explain things very well. This one is very easy to set up, once one understands the use of common events, variables and switches but I’ll still post this here in case someone has a hard time figuring out how to implement it.

Edit May 15th, 2020:
New Demo!
You can study how this demo was made and learn how to event a flashlight system.
Enjoy!

Hello! I really love this method and hope to use it myself.

I've got it all in place without issue, but I was curious - is there a way to link it to player steps instead of frames?
Depending on a players monitor or settings, frame rate can vary quite a bit, but steps are pretty universal.

Anyway, I was just curious.

Thanks again for this tutorial!

@ddblue I'm happy to know that you found this tutorial helpful. The reason I used frames was because I wanted to give the battery a life I.e the battery can die after particular time of usage. If we used steps, them it wouldn' work. Because, suppose, the player is standing in one place for quite some time. But the flashlight is on. Will the battery life be consumed? No. Because the batter's life is linked to th players steps. That didnt seem ok to me so I used frames instead. Though frame rates can vary in different computers, the overall playtime will remain constant because if frame rate is less, the game will run slow and if it' high,it'll run fast. Similarly, the battey life will exhaust slowly or faster depending on the speed the game runs in. That means,it' pretty much constant. That' Why I used frames. Well... This answer is pretty big but I hope you understand now. :)

Thank you very much for clarifying :)

Intense stuff, Hyouryuu! Though I'm using a torch system for my WIP game, it's still what I need to have torches that can be expended over time when entering the dungeon. Otherwise, I feel a lantern and lamp-oil system could work in place of a flashlight and batteries. Am working on a spiritual successor to the classic Wizardry CRPGs, heheh. :p

I'm glad you liked the tutorial. This method can be used for lamps and oil too ^^ and I think it's definitely possible to make torches used up over time. Perhaps it's easier than this because the batteries part was pretty complex haha. Good luck with your game! :D

Hi! I just started using RMMV and I'm kinda new to this. Your tutorial has been really helpful, unfortunately, I can't seem to make it work. The flashlight doesn't appear in the player's inventory once he aqcuired it.

Oh, and now I've been getting an error : Cannot read property 'clearLightBatlers' or undefined

Hello! I haven't worked with this flashlight system for a long time. So even I forgot how I did it. ^^; But I'll look at the events and see how it was made. But the flashlight is supposed to appear in the inventory. Can you send me screenshots of the events? Or I can send you a demo. Yeah, I think that will be better.

About the error, I don't think the engine will show an error like that? It's most likely caused by the lighting plugin you're using. I will post the demo here after I make it. You can study it and see how things work.

A demo has been added. Please see that instead of the old tutorial.

It says the demo is not available anymore.

Yep, The link is down!

I sorta deleted it from my computer along with a ton of others to make space.
I'll reupload once I've made a newer project.

Thanks a lot, ^^ And take as much time as you need just reply here when you update the link:kaoluv:

Read the comments inside the events for better understanding.

:kaohi:Thank you !

No problem. Don't hesitate to ask questions if you have any ^^

Thanks for the tutorial! Could you make one for a gun flash (the gun makes light when shooting)?

Btw I tried your flashlight method but i have an issue. When I press F instead of turning the flashlight "on" it just gives me a flashlight item. Everytime I press F it just gives me a flashlight item and i can keep giving myself a flashlight.

Hi, I'm kinda busy these days. I don't think I'll be putting out anything new. But I'll look into the issue you mentioned when I have time.

Edit 13/5/2023: I tried my demo. I don't see any problems :/
