Tile Map Tutorial Error
« on: May 30, 2014, 03:46:30 pm »
I am getting the following error on several lines when I follow the tutorial for a tile map, at first I thought I might have typed something wrong, but after copying a pasting it, I got the same error.

This is the error:
Code: [Select]
1>LoadMain.cpp(36): warning C4244: 'argument' : conversion from 'unsigned int' to 'float', possible loss of data

Please read this.

Code: [Select]
1>LoadMain.cpp(36): warning C4244: 'argument' : conversion from 'unsigned int' to 'float', possible loss of data

That's not an error, that's a warning that you're implicitly converting one numeric format to another, which could affect the correctness of the number. A quick Google search of the message would have helped you find out more information.

Ahhh, ok, thank you. I looked through my Debug Log and found that this is what is actually stopping the build:
Code: [Select]
1>LoadMain.cpp(26): error C2108: subscript is not of integral type

Well now we have the error, what was the code again?

The actual error, shown above, comes on this line:
Code: [Select]
int tileNumber = tiles[i + j * width];

First result of Google search.

Array indices must be integers. Your i + j * width calculation is producing something other than an integer, most likely a double.
