Unit to integer

[krainert]

Hey people,

I need to acquire unique integer ID's for units. Is there a clever way of doing this?

Thanks.

[ljass]GetHandleId[/ljass]

Though, depending on your needs, even better solution could be some unit indexing system. There's quite a few of them around.

Install one of these and use [ljass]GetUnitUserData[/ljass]

Thanks.
How is it that GetHandleID is inferior?
Also, if I use GetHandleID, is there a way to convert from a handle to a unit?

[ljass]GetHandleId[/ljass] return the id of that handle, which is much bigger then just 8190.

I think you might be able to with fogstate typecasting. (I2U see the typecasting library by kingking) However, that is pretty slow and not really necessary. Instead, you should just use a unit indexing system because:
1) It will allow you to use arrays really easily to store unit data.
2) You can retrieve the corresponding unit through GetUnitById() [which is what you are trying to do]

GetHandleId() is good, but you usually end up having to use hashtables unless you subtract a high enough number to make it in the array range. (0x100000) That method is unreliable though.

Thanks again. I think I got the non-LUA UnitIndexer to work, but is using this over the LUA one a problem?
(The LUA variant required some other LUA stuff which failed installation)

Well, Nes' added all that LUA requirements to avoid rawcode collision, that's all. Using the non-lua one is just fine.

Great, thanks. I'll be back once it turns out I somehow managed to screw everything up.
