i've only used for loops in scripts i gotten elsewhere so i don't really understand how it works, i have a large number of textures that i wanted to apply to a link set in sequence so i wrote this script to try to do that to apply a texture to a face and then move to the next link when all the faces are covered on the current link. From: someone default
{
state_entry()
{
integer link = llGetNumberOfPrims();
integer face = 6;//7 faces on prim starting with 0 so highest index there is 6
integer i;
integer textnum = llGetInventoryNumber(INVENTORY_TEXTURE)-1;//get the number of textures in the inventory, then subtract 1 to get the index for the last one
for ( i = textnum; i > -1; --i)
if(face == -1)//if it passed the lowest face go to the next link and start over
{
face = 6;//7 faces on prim starting with 0 so highest index there is 6
--link;
}
string name = llGetInventoryName(INVENTORY_TEXTURE,i);
string uuid = llGetInventoryKey(name);
llSetLinkTexture(link,uuid,face);
--face;
}
}
i'm using a set of cubes cut to 0.00 and 0.750 and i made sure there's enough faces to hold all the textures. but each time the script starts i just get an error [18:09] Object: Could not find texture '00000000-0000-0000-0000-000000000000'. i tried applying it with just the name but i was getting [18:04] Object: Could not find texture ''. can anyone spot the problem and help me fix it? thanks |

Do you have full copy/mod/transfer perms on the textures in the object's inventory? If not, then llGetInventoryKey will return NULL_KEY. Of course, that shouldn't affect llGetInventoryName.....

yes they're full perm sculpt maps, i'm trying to use it to display all the maps so they'll already be loaded as i flip thru the types

sorta figured out what i was doing wrong, was missing a set of brackets to determine what needed to be done with the loop, so i guess it was causing the index number to not change and i also reverved the increment calls (--i changed to i--) From: someone default { state_entry() { integer link = llGetNumberOfPrims(); integer face = 6; integer textnum = llGetInventoryNumber(INVENTORY_TEXTURE)-1; integer i; for (i = textnum; i > -1; i--){ if(face == -1) { face = 6; link--; } string name = llGetInventoryName(INVENTORY_TEXTURE,i); string uuid = llGetInventoryKey(name); llSetLinkTexture(link,uuid,face); face--;} llOwnerSay("done"  ; } } worked perfectly |

played with it some more so i could view them all on one side, and used the XY setup script to shape the prims From: someone list faces = [3,7,4,6,1]; default { state_entry() { integer link = llGetNumberOfPrims(); integer face = 0; integer textnum = llGetInventoryNumber(INVENTORY_TEXTURE)-1; integer i; for (i = textnum; i > -1; i--){ if(face == 5) { face = 0; link--; } string name = llGetInventoryName(INVENTORY_TEXTURE,i); string uuid = llGetInventoryKey(name); integer facenum = llList2Integer(faces,face); llOwnerSay("link " + (string)link + " face " + (string)facenum); llSetLinkTexture(link,uuid,facenum); face++;} llOwnerSay("done" ; } } |

From: Ruthven Willenov ..and i also reverved the increment calls (--i changed to i--) Just as a side-note, if you're not using the variable in a function call or as part of some larger equation, this bit really doesn't matter - it's the same either way. If you do this, the 'DoStuff' routine will get passed a 0. i = 1; DoStuff (--i); If you do this, the 'DoStuff' routine will get passed a 1. i = 1; DoStuff (i--); Either way, i is equal to 0 after DoStuff returns. As the last bit of a 'for' statement, using pre- or post- doesn't matter. |
