Sim Map

Does anyone know how to retrieve the sim map for use as a texture? I want to do this programatically so as to be able to pull and use the map for whatvever sim I am in.

I'm not sure there is a way to do it via LSL. There might be a way to use an http_request call, but I'm not an expert at that at all. The only way I can think of doing it is to capture a screen shot and crop, then upload as a texture.

I've seen items in which it is done dynamically. If it requires an http_request or even an outside PHP script I can do that just need enough information to be able to make it happen.

If you've seen it done, it most likely comes form the slurl page on secondlife.com. I'd assume it would work like grabbing a profile picture, but that's just a guess.

Try this .... It grabs the map for the current sim and drops it on a prim, also reads from a notecard in the object's inventory. The notecard should consist of pairs of lines, the first one describing a potential LM in the sim and the second line consisting of a URL in the form secondlife:///app/teleport/MySim/105/122/34/. The lines are read into chat, where the URLs appear as direct TP links.

I put it together as a friendly map/TP system for an orientation area. Obviously, you can strip out the notecard stuff to get just the sim map that you're asking about.

Or the sim map particle projector that is on my user page. All you have to do is strip the particle stuff out.

key httpRequestId;
float mapSize = 3.0;
float mapHeight = 3.0;
string mapTexture;
string URL = "http://www.subnova.com/secondlife/api/map.php";
 
mapParticle()
{
	llParticleSystem([
		PSYS_PART_FLAGS, 0,
		PSYS_SRC_PATTERN, 4,
		PSYS_PART_START_ALPHA, 0.50,
		PSYS_PART_END_ALPHA, 0.50,
		PSYS_PART_START_COLOR, <1.0,1.0,1.0>,
		PSYS_PART_END_COLOR, <1.0,1.0,1.0>,
		PSYS_PART_START_SCALE, <mapSize,mapSize,0.00>,
		PSYS_PART_END_SCALE, <mapSize,mapSize,0.00>,
		PSYS_PART_MAX_AGE, 1.20,
		PSYS_SRC_MAX_AGE, 0.00,
		PSYS_SRC_ACCEL, <0.0,0.0,0.0>,
		PSYS_SRC_ANGLE_BEGIN, 0.00,
		PSYS_SRC_ANGLE_END, 0.00,
		PSYS_SRC_BURST_PART_COUNT, 8,
		PSYS_SRC_BURST_RADIUS, mapHeight,
		PSYS_SRC_BURST_RATE, 0.10,
		PSYS_SRC_BURST_SPEED_MIN, 0.00,
		PSYS_SRC_BURST_SPEED_MAX, 0.00,
		PSYS_SRC_OMEGA, <0.00,0.00,0.00>,
		PSYS_SRC_TEXTURE, mapTexture]);
}
 
default {
	state_entry() {
		httpRequestId = llHTTPRequest(URL + "?" + "sim" + "=" + llEscapeURL(llGetRegionName()),[], "");
	}
	http_response(key request_id, integer status, list metadata, string body) {
		if (request_id == httpRequestId) {
			mapTexture = body;
			mapParticle();
		}
	}
}
 

Which leaves you with :

key httpRequestId;
string URL = "http://www.subnova.com/secondlife/api/map.php";
 
default {
	touch_start(integer n) {
		httpRequestId = llHTTPRequest(URL + "?" + "sim" + "=" + llEscapeURL(llGetRegionName()),[], "");
	}
	http_response(key request_id, integer status, list metadata, string body) {
		if (request_id == httpRequestId) {
			llOwnerSay("Sim texture uuid = " + body);
		}
	}
}

Thank you, that worked perfectly.

FYI, you may want to read comments by Philip & James Linden in this thread:
/352/51/303761/1.html

from Philip Linden (post #96)
and James Linden (post #127):

Philip Linden's latest project is the "more open than the regular viewer" viewer which includes the long-awaited ability to fetch textures visa straight HTTP. There is a really aggressive schedule to turn this thing into a release, freeze is supposed to be in a few weeks. So, if and when in-world map tiles go away, there should be a replacement out there.

Meanwhile, in-world map tiles aren't on the schedule to go away now, because all the currently released viewers still need them to display the map. the in-world map can't be changed over until Philip's texture project is completed and integrated into all viewers.

Soooo, at some point those map scripts will probably break, but not before there is a way to fix them.
