This is a CETrainer by mgr.inz.Player :

The animating background not work in CE 6.5.
Is it cause by alpha blend setting or other ?

This is because Dark Byte switched from Lua 5.1 to 5.3.
In Lua5.1, function lua_tointeger truncates floating-point values ( like 10.3 ==> 10)
From what I see in lua5.1-32.dll, there is cvttsd2si ("Convert Scalar Double-Precision Floating-Point Value to Signed Doubleword Integer with Truncation")
In Lua5.3, function lua_tointeger works differently. (like 10.3 ==> 0). So, my script has to be updated. Bunch of math.floor functions. But, it might add some extra overhead...
Hmm, maybe it would be better to add such function to LuaHandler.pas:
| Code: | function lua_tointeger_alt(L: Plua_State; idx: Integer): lua_Integer; cdecl;
var
isnum: Integer;
begin
result:=lua_tointegerx(L,idx,@isnum);
if isnum=0 then
begin
result:=trunc(lua_tonumberx(L,idx,@isnum));
if isnum=0 then raise exception.create('Not valid integer');
end;
end; |
And use it in all places where are high chances that user will use calculated values.

Thank mgr.inz.Player
So it's better to re-read for some Lua 5.1 function and adapting it all to Lua 5.3 or doing a debugging. Because some of my trainers made by Lua 5.1 also not running in CE 6.5 (Lua 5.3).
Thank again for solution and information.

Some can be easily fixed. Below cetrainer file has those math.floor in some places.
But, I think DB could do some changes in lua.pas to make CE6.5 more backward compatible.
For example, I tried below function and compiled CE myself:
| Code: | function lua_tointeger(L: Plua_State; idx: Integer): lua_Integer; cdecl;
var
isnum: Integer;
begin
result:=lua_tointegerx(L,idx,@isnum);
if isnum=0 then
begin
result:=trunc(lua_tonumberx(L,idx,@isnum));
if isnum=0 then result:=0;
end;
end; |
starsAnimation and NFOWindow (my old Lua scripts) now work normally.
I already mentioned about this in "CE 6.5 bugs" thread.

Many thanks, Now I can learn where is different in script coding by comparing your two CT files.
This is very helpful for me to learn more.

Re-download CE6.5 from main page and reinstall.
