RMS resource thread

Durokan · Post by **Durokan** » 18 Jan 2016, 05:29

I have decided to make a thread dedicated to random map script resources. I will link stuff I find useful here.

Attached is a reasonably well annotated RMS that I created in order to help people get their bearings within a RMS if they have never seen one before. It probably will not teach you everything you need to know about everything, that is what the RMS guide is for. It will; however, tell you what a certain block of code is for and what it does. In conjunction with the RMS guide it should make it easy to write your own maps. Place it in your RM3 folder, which will be in your install location. drive\Age Of Empires 3\bin\RM3\mapname

Edit: I found an improved version of my desk-top picture on aoe3 heaven. Shoutout to Kyle Leach (10 years later)

[spoiler=original image]I have a paper copy of the following picture sitting next to my computer. (Very useful for ball-parking placement areas)

Here is a great guide on how to create maps

Should be x and z

It should have been doable from the scenario editor. F*ck microsoft.

its *really* hard to make random maps work in an editor. :c
Though I guess if you didn't want randomness from a gameplay perspective an editor would be fine.

It is kinda disappointing though. :c

Yeah exactly, I forgot to mention the randomness. But wouldn't it only apply for treasures, herds, mercs etc ? Because the general design would remain the same.

everything is randomly generated each time the map is loaded. The curvature of a coast, for example changes every single time you load it unless you set the edge to be perfectly straight. Coding things to be "generally the same" is incredibly hard when using a non-dynamic editor. I guess there could have been some sort of interface that tells a painted area to do something within certain boundaries, but it would have been really, really, hard to do and use a lot of resources that ES thought was better spent on other stuff, like making the game. RMS haven't ever been supported either to my knowledge.

If the game had supported RMS through an editor it would probably have been the equivalent of a scenario, where there is no fluctuation.

What's a good way to place starting mines in a more strict position? For example if one player gets 1 mine in front, and 1 mine a bit further away behind the TC, I want the opponent to get the exact same mine placement to make it fair.

- Is it possible to randomly generate, but mirror the placement for all players?
- Is it possible to strictly place 1 mine in front and 1 mine behind TC? (Or 1 mine to the side, and 1 mine on the other side further away etc.)?

As it is now on the maps, as far as I can see, it's quite random

Remember, you can pretty do whatever you want on rms map, it's just more or less difficult to code.

Yes, this is why I ask

Maybe "possible" is the wrong word. Possible without spending countless hours

Cash question right there!

I don't know how it works, but Garja uses the function "rmCreatePieConstraint" and that has the ability to put in rmDegreesToRadians, which sounds like it allows something with that constraint to be put in a specific area relation to the spawn location. Example hypothesis code for the first gold constraint:

int startGoldTop= rmCreatePieConstraint("startGold Top", tcLocX, tcLocZ, 0.0, 20.0, rmDegreesToRadians(0), rmDegreesToRadians(90));

Theoretically that should set up an area to have a goldmine placed within a 20 meter radius from the degrees of 0 to 90.

If you were to set up random number generators for the distance between the town center, set up random numbers to select from which quadrant (0-90, 90-180, 180-270, 270-360) you want to place the mines, and keep them the same for both players, it could probably work well. You would then do another mine with the same random distance divided by two or something like that, that also uses the opposite quadrant.

Wow, that's a pretty handy pie function, thanks!

are there more documentation of these functions (except in the code of course) because I couldn't find this one in the guide in hyena studios.

Anyway I played around a bit without it so I used it like this, maybe uglier, but it works pretty damn well. might just need some map size variable too. south-north team placement in this case:

int k = 1;
if (rmPlayerLocXFraction(i) > 0.5) {
k = -1;
}
rmPlaceObjectDefAtLoc(playerGoldID, 0, rmPlayerLocXFraction(i) + 0.02*k, rmPlayerLocZFraction(i) + 0.02*k);

I managed to get the mines spawning towards the enemy, very close to TC 10 times out of 10, with minimal variation in distance, 1vs1, 2vs2, 3vs3 etc. I'm Just sharing in case anyone else is interested

Looks good! I don't know of any other documentation, other than I use it to avoid the edges of the map. (only placing things within a radius of .48 of the map in a 360 degree circle) Garja uses it for alot more than I do, check out Kamchatka. I know you asked for stuff outside of a map, but it uses that alot for setting up map areas.

In your case you can use FairLoc commands, which are exactly designed for your request. This command is explained in the hyena studio guide.
Here is an example : mineb = mine back ; minef = mine forward
