RNG and Weather

I don't know if I should even bother fixing it as it seems like interdpth has some snazzy ASM plan which makes my method look pretty rudimentary. With mine, you have to add a level script for every single map that you want random weather on. Though the fact that you don't have to edit indoor maps (unless you want it to rain inside) makes things easier, it's still a hassle.

Still, I'm interested in seeing what you guys come up with. I could try to help out but my ASM knowledge is pretty pathetic.

Best of luck.

The only thing he is planning on doing is making it so your or my script is called every time a map is loaded. I'll keep you updated. I think I have you added on MSN? :\

[interdpth]

SOmeone make a script that everyone agree's on, and i'll hack the level loading routines and make it execute.

DEAL?

I looked through the script and I realized that a "goto @end" is also necessary at the end of @sunnyscript and its corresponding scripts.

This hasn't been fully tested yet but it's nearing the final stages. Does anyone have any other ideas that they want added? I've already added manual override and the ability to disable the random weather at any time but if there are any other features that you think would be nice to have, just speak up and I'm sure we can figure out how to implement them.

I guess we'll need to try and fully test it if you're satisfied. I know I am.

Well, Darthatron and I have been talking and we're working on a better version. If you have MSN you can join us, actually.

edit: We think we're nearing in on a final version but we're still testing it. We'll keep you updated.

edit2: Well we think we have finally agreed on a script. We've tested it too and as far as we can tell, it works like we want it to. Now all we need is for interdpth to work his magic.

Here's the script:

Of note, is it fully necessary to define the ONE weather byte that the script activates on AND ensure it doesn't activate in certain areas? Sounds like an unnecessary measure when it's up to the hacker to set which weather byte activates it.

[0m3GA ARS3NAL]

Well well well, stuff happened pretty fast!
I wasn't even here for the initial idea pitch, oh well.
I've tried out this script a bit on my PSP, and all goes well, well indeed.
Though I had an idea...
What about snow?
I know for a fact that people nowadays have the strangest fascination with snowy maps in a ROM hack, and if someone makes a snowy mountain, how would this random weather be incorporated...
I guess as of yet one could simply change the "Storm" and "Rain" to things like "3 Snowflakes" and the Ash snow used in R/S/E...
But that would require compiling a completely different script, and if someone were to cross maps while things are stormy, to a map intended to have the chance of snow, things may get a little buggy.

If you can come up with the chances of the snow weathers happening then I would have no problem adding it in. I, however, am far too lazy to think of those values up.

[0m3GA ARS3NAL]

Well, the sown weather would be the one thing that would need to change depending on the map itself, what it looks like, I mean, even I could add that in myself, I know my way around a script, what I mean, is the off chance someone decides to want to use this for snow too.
Adding in a probability wouldn't help one bit, since even then snow could happen in a place such as a beach, or a rain forest, not exactly natural.
The best thing I can come up with is a variable the user would have to set themselves.... (Aside from @setup, where V_SNOW is set to 0, which can be removed fairly easily)

I somehow don't find this to be "natural" weather anymore.

Of note, Matt, will you be calling this script from the header while leaving it modifiable?

It was my understanding that the script would be accessed by the ASM routine, making the script modifiable at any time.

Actually, interdpth also wanted to get rid of the "check 0xF" part so if you don't want that part in the script either, then can just remove it without harming anything. However, I would argue that the "check 0xF" function is beneficial because it allows a hacker to make a map use a fixed weather condition for a map if they want without having to change the map type to indoors or something like that. It may not be the most realistic if a town always has rain but I could imagine that hackers might enjoy that option.

Eh, it's really up to you and if you don't want it, then just use the modified script that Darthatron posted.

Gah! You went over the character limit! My beautiful header text!

In my opinion, I think snow is just unnecessary. If the only conditions that the script can alter between are "3 snowflakes" and "snowing", it just doesn't seem worth it to me. I think the hacker would be better off setting a fixed condition seeing how they know how the map is going to look and can decide whether light or heavy snow is more realistic.

[altariaking]

where do you put the script after compiling it?

That's what he told me he was going to do.

This.

Right now, in a level script on every map.

Meh, just a suggestion you know, if someone wanted snow to happen, it could.
(Besides, I decided not to include 3 Snowflakes, since it isn't exactly... ideal, so to speak.)
The 3 Snowflakes weather is odd, and only seems to work half the time.

I do agree though, snow is a bit unnecessary, just thought I would include it for anyone who wants it. (And I know, someone out there wants a more natural snow, lol)
If only we could make MORE weather types...

[altariaking]

whenever I try to compile it says missing define

[Megiddo-san]

Are these the correct settings for implementation? 1. Use offset of @main 2. Use an 01 setmaptile script 3. Set map weather to 0F I haven't gotten it to do anything yet. Probably some key detail I missed.

Remember to initialize the weather variable (0x7000) to either 0x2, 0xB, 0x3, or 0xD (sunny, cloudy, raining, and thunderstorm respectively).

So how's the ASM part of this idea coming along? Last time I checked, interdpth said that he was going to add a "hook" to the routine that runs every time a map loads. Is that still the plan? And if so, how is progress on that so far?

It should actually be between 1 and 4, as stated in the comments on the line that defines the variable.

OR 5 if the person is using the snow modded one! lol...

Ah, gotcha. I'll try that.

Think you could make a video tutorial on this? I think it'd help me a bit more as I am having a bit of trouble understanding exactly how to do this.

// Natural Weather Script!
//----------------------------------------------------------------
// By colcolstyles and Darthatron (3/1/2010)
//----------------------------------------------------------------
// This script will create a system which aims to simulate the
// "real world" weather by randomly switching between weather
// effects (sunny, cloudy, raining, and thunderstorm). The odds of
// a change occurring depend on the current weather (i.e. it is
// more likely to start raining when it is already cloudy than
// when it is sunny). However, random weather will only occur if
// the weather type on the player's current map is set to 0x0F.
// Because of this, the hacker can make a map use a preset weather
// condition and be exempt from random weather.

If you can come up with the chances of the snow weathers happening then I would have no problem adding it in. I, however, am far too lazy to think of those values up.

That script you have there, where exactly do you put that in the game? Or do you just compile it... I'm such a n00b.

Also....

Compile it anywhere, then put it in a level script.

Um so question.
1.) Is this open to the public
2.) What is a level script
3.) Where do you put it on a map
4.) Can you use xse and Am1.92 to insert it into the game?

1) Not technically
2) This isn't the place to be asking that
3) I don't really feel like explaining
4) Yes but, as I said, it's not finished yet. If you wait a little longer, there will be a patch that won't require using XSE or AdvanceMap to use :)

A level script, okay. So I have to put it on a level script for each map I want this random weather to be on?
