7 form.destroy()

Check an object's class[edit]

1 local form = createForm(false)
2 
3 if form.getClassName() == "TCEForm" then
4   print("This is a Cheat Engine form")
5 end
6 
7 form.destroy()

Get the address of a field[edit]

1 local form = createForm(false)
2 
3 local address = form.fieldAddress("FName")

7 end
8 
9 form.destroy()

Get the address of a method[edit]

1 local form = createForm(false)
2 
3 local address = form.methodAddress("Show")
4 
5 if address ~= nil and address ~= 0 then
6   print(string.format("%X", address))
7 end
8 
9 form.destroy()

Get a method name from an address[edit]

 1 local form = createForm(false)
 2 
 3 local address = form.methodAddress("Show")
 4 
 5 if address ~= nil and address ~= 0 then
 6   local name = form.methodName(address)
 7 
 8   print(name)
 9 end

11 form.destroy()

Destroy an object[edit]

1 local form = createForm(false)
2
