I want for staff to be able to place houses over things such as rocks and little flowery things, is there any way I can do this?

Use the different flags to make it possible (CRMULTI_IGNORE_OBJECTS): http://docs.polserver.com/pol097/singlefunc.php?funcname=CreateMultiAtLocation&xmlfile=uoem.xml#CreateMultiAtLocation.

ok, got it to work, thanks.

One question though...

so, with
const CRMULTI_IGNORE_MULTIS := 0x0001; //ignore intersecting multis
const CRMULTI_IGNORE_OBJECTS := 0x0002; //ignore dynamic objects
const CRMULTI_IGNORE_WORLDZ := 0x0004; //ignore standability,relative Z,world height
const CRMULTI_IGNORE_ALL := 0x0007;


If all does all of them, does world do objects and multis? and objects to multi's?

CRMULTI_IGNORE_MULTIS - Ignores other houses and multis so you can essentially place 2 within eachother.

CRMULTI_IGNORE_OBJECTS - Ignores items and characters in a spot and places the multi anyway.

CRMULTI_IGNORE_WORLDZ - Ignores uneven terrain, rocks, flowers, and the world height.

and of course CRMULTI_IGNORE_ALL does all of them.

No, ALL is binary OR of MULTIS, OBJECTS, and WORLDZ. You can combine them yourself if you like.. for example

isn't that supposed to be

No. If you would do something like

it would be wrong if you used +. if you use flags, always use binary OR (or AND, depending on what you're trying to do.

In this special case, because in binary each flag is its own bit:


using a binary OR ( | ) or using normal addition ( + ) will result in the same value.
1 | 2 = 3
0001 | 0010 = 0011

-and-

1+2=3
0001 + 0010 = 0011

However, because these are flags, only the binary OR operation is acceptable, and addition can lead to errors. eg:



So, in short, when combining flags, ALWAYS ALWAYS use the OR operator, and not the addition operator.
