strange in if

[omar shaaban]

well o just in the main
i tell him if (mymap[j]==2)then do something AND IT WORKS but i made a function and in the function he checks mymap[a]==1 and it doest work and i am sure that my map[a]=1 but why doesn't he give me true!!?

... it can't be equal to 1 then. Would != 2 work for whatever you are doing?

If not perhaps you could printf your variable to see what it really is.

[mispunt]

And could you give more code? it is hard to say were the problem is.

The first step is indeed, print the value of map[a] to the screen.
And second, does the function get the right values?

[omar shaaban]

ahh yeah the value of mymap[3][3] is 0 why it is supposed to be one anyway here is my map:

Code: Select all

 int mymap[20][20] ={{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}};

i found the problem it was that there were 2 maps one before the main and other in the main so this was the problem but it worked now but when it worked i found the game crushes again so i searched until i found the problem in this code in the loop(of the engine loops in the game):

Code: Select all

if (node)//gets node name
{

    nameb=node->getName();//i mean this line
   
}

so after i deleted this line the game worked but why did it make problems it seems to work fine before i fix the map bug!!!

[Dances]

node is probably not initialized. Perhaps that node WAS you duplicate map.
