std::vector?!

[psiko_scweek]

Alright,

im having a problem with my game. whenever i try to compile i get an error with the following code:

Code: Select all

std&#58;&#58;vector<PlayerBlocks> VerticalBlue;
for&#40;int i = 0;i < NumberOfBlocks;i++&#41;
&#123;
VerticalBlue.push_back&#40;PlayerBlocks&#40;0,0,NULL&#41;&#41;;
&#125;

and im getting the following errors:

"expected unqualified-id before 'for'"
"expected constructor, destructor, or type conversion before '<' token"
"expected constructor, destructor, or type conversion before '++' token"

any suggestions?[/code]

[hlide]

well, i suppose you add "#include <vector>" before ? that your file is suffixed .cc and not .c ? that you declared your class PlayerBlocks ?

[psiko_scweek]

yes!

i did include the vector in the header...

my suffix is cpp is that ok?

and PlayerBlocks is declared. any other suggestions?

[psiko_scweek]

i tried to change the extension on the file and it is still not working...im lost! im using SDL would that prevent it from working?!

Is "PlayerBlocks" declared somewhere?
A class or struct?

You cant have a for loop outside of a function / in declaration space. Put the

for(int i = 0;i < NumberOfBlocks;i++)
{
VerticalBlue.push_back(PlayerBlocks(0,0,NULL));
}

part inside your main() function.

^^^ what he said

Also you need to add an empty constructor to your PlayerObject. This is required because the vector will instantiate PlayerObject objects.

// empty constructor
PlayerObject(){}

Plus, I think you might want to have a look at this topic (about C++ includes), because your errors sound sort of familiar :

ok this isnt fair! i moved the For loop to my main function and it solved my compilation problems now nothing works though!!

lol damn it
