GameMonkey problem

I have switched to GameMonkey recently because it's easier to compile and use it on my app. The implementation works, but somehow I'm stumbled with a problem which is reading the script from a file.
I have a test.gm file that contains the following script
and I use the following code to read the file and run the script
Code: Select all
std::string s;
std::ifstream file;
file.open("test.gm");
while(!file.eof())
{ getline(file, s); }
file.close();
gm->ExecuteString(s.c_str());
Unfortunately nothing happen. Supposingly it should print the word "yo".
However if I don't read the script from file and include it in the source code, it works like charm
Code: Select all
std::string str = "print(\"yo\");";
gm->ExecuteString(s.c_str());
can anyone spot any error from my code? thanks in advance.
I have asked the same question on GameMonkey forum and waited for days but the forum seems dead.

I know nothing about gamemonkey. But anyway:-
- why do you escape the quotes (\") in the test.gm file? Does gamemonkey require it? (I'm guessing not)
- print out your getlines for debugging. and print out the final "s" before calling ExecuteString. See what it contains.
- doesn't getline overwrite the string each time? So you will only end up with the last line in the file stored in s (which might be a blank line).
So try:
Code: Select all
std::string s;
std::string temp;
std::ifstream file;
file.open("test.gm");
while(!file.eof())
{
getline(file, temp);
s += temp;
}
file.close();
cout << "File contents: " << s;
gm->ExecuteString(s.c_str());

I don't know very much about GameMonkey either, but I do know that it does require the escape characters in this case. (I only did a very short tutorial on it) Sorry, I have no other information to share.

thanks! it works now. the escape characters is not required if your script is stored in a text file. ahh didn't know getline overwrite the string each time.
again, big thank!

Hey you made me discover GameMonkey! Thanks.
I'll surely use it instead of doing my own code parser to save time. I find it better than Lua because of its C style & little size. I had never used Lua but when looking at it, it looks like pretty (too) huge.

i tried Lua and it's very hard to bind (for me) even if use the luabind which requires boost. very huge.
