I'm quite new to lua scripting ahd therefore don't know much about it, all i know is that i need 2 CE clients and a shared memory block
Code:
x=allocateSharedMemory("abc", 4096)

What do i have to do next? I think i now have to tell CE to put the addresses into that memory block and then i have to tell the other CE client to grab information from that block, but how do i do that?

Design a structure layout containing all the data you wish to share.
e.g:
0:x
4:y
8:z
12:health
16:ammo

Then use a timer in one CE that reads the addresses you're interested in into x
e.g:
writeInteger(x+0,readInteger(addressofxcoord))
writeInteger(x+4,readInteger(addressofycoord))
writeInteger(x+8,readInteger(addressofzcoord))
writeInteger(x+12,readInteger(addressofhealth))
writeInteger(x+16,readInteger(addressofammo))

and in the other CE read out the memory
xcoord=readInteger(x+0)
ycoord=readInteger(x+4)
zcoord=readInteger(x+8)
health=readInteger(x+12)
ammo=readInteger(x+16)

and write them where you wish

To make it easier I am trying to sync the xcoord and the zcoord of the same process (yes i know that this makes no sense for gameplay and i also know that there is a way easier way to do it but i want to learn this method)

Code:
x=allocateSharedMemory("testblock", 4096)
writeInteger(x+0,readInteger(20D05D50))
zcoord=readInteger(x+0)]


After executing this I got an error

Script Error:[string "x=allocateSharedMemory("testblock", 4096)..."]:2: malformed number near '20D05D50'

so i tried some stuff and ended up putting the address into " " (idk if this makes sense, as i said i'm new to lua scripting and just tried random stuff until the error dissapeared)

now when i execute the code nothing happens. What do i have to do?
