Numbers

> print(2+2)
4
> print(2-7)
-5
> print(7*8)
56
> print(7/8)
0.875


Numbers not rounded into integers. They are floating points or "real numbers"
Assign values to variables using = operator

> x = 7
> print(x)
7


The variable x is created when the number 7 is assigned to it. use the print() function again to print out the value of x. now we can use the value in x for other calculations.

> x = x * 9
> print(x)
63
> print(x*2) -- will not change the value of x
126
> print(x)
63

Strings

print("hello")
hello

Assign variables to strings
who = "Lua user"
> print(who)
Lua user


You can concatenate (join together) strings together using the .. operator between two strings.

> print("hello ")
hello
> print("hello " .. who) -- the variable "who" was assigned above
hello Lua user
> print(who)
Lua user

Notice that the .. operator does not change the value of message unless the = assignment operator is used, just like numbers.

> message = "hello " .. who
> print(message)
hello Lua user

Unlike some other languages, you cannot use the + operator to concatenate strings. i.e.:

> message = "hello " + who

Test Script:

cmd('unbind space')
clientbase=getBaseAddr "client.dll"
vguibase=getBaseAddr "vguimatsurface.dll"
function ground() return (readmem(clientbase+0x51D0F0,4)~=-1) end
function gui() return (readmem(vguibase+0x117314,4)==1) end
jump=(function(bool) cmd((bool and "+" or "-").."jump") end)
while keyDown(35)==0 do
jump((ground() and (keyDown(32)~=0) and not gui()))
wait(5)
end
