Draw Missing!?

[Laurent]

Your code is correct. Maybe the current working path is not the one you think it is.

[qsik]

i fixed it! oddly, the jpg file wouldnt load but converting it to a png solved the problem

[qsik]

*bump for update email

[qsik]

how would i get the path of where the exe is? that way i can load images and music even if the name of the folders change

also, i switched to using arrays, so i have sf::Image other[5] instead of sf::Image Opening and such, but the image does not load for some reason...it did before

heres my code, i cant seem to find why it wont work plz check for errors due to misused/wrong syntax

heres my code, i cant seem to find why it wont work plz check for errors due to misused/wrong syntax

You need to tell us exactly what's not working as expected and post just the relevant code.  You can't post your entire app, ask "why doesn't it work?" and expect meaningful help.  You need to help us help you.

[quasius]

how would i get the path of where the exe is? that way i can load images and music even if the name of the folders change

also, i switched to using arrays, so i have sf::Image other[5] instead of sf::Image Opening and such, but the image does not load for some reason...it did before

Getting the working directory is OS-specific.  You will need to google "get working directory c++ <OS name>."
As for arrays of images, that should work fine.  You probably have a problem somewhere else.  Are you sure you are indexing them correctly?

[zarka]

if you have a folder structure like this:

Code: [Select]


game_folder
| - exe
| - data_folder
     | - img.png

you could in your code write img.LoadFromFile("data_folder/img.png");

This will work on most operating systems(at least windows, linux and mac OS) and is how most people do it

[zac]

Getting the working dir in Windows uses the function "GetCurrentDirectory". The description of this function will be at msdn.microsoft.com .
In Linux, you have to usw getcwd() (take google/view die-linux manpages)...
by the way, you could use relative paths...

To get the real directory of your executable file in Windows, you use first:
GetCurrentProcess() to a call to GetModuleFileNameEx.
Again, both functions are described at msdn.microsoft.com .

[qsik]

using the SVN version of SFML with VC 2008, i cant get my images to load (checking the image variables when debugging shows them to be empty )
i posted my code to see if anyone could find anything wrong with the code (as in incorrect syntax)

[Avency]

I'd suggest that you should use relative path names, get the working directory or use some sort of system variable instead of using hardcoded pathnames...seriously!!!
Is there any error output (like "can't fopen")?
Maybe your "Convert" function produces a  unwanted result.

[qsik]

yes, but the Opening sprite does not appear even though it does it has a hardcoded path, my question is why it wont appear

[qsik]

u were right, the for loops in my LoadImages(); was causing my sf::Image Opening to not load...odd

for images, are vectors better than arrays?

otherwise, im not sure how to mass load images in succession, ex. my program looks through subfolders for images labled Slide1, Slide2, ... and so forth

how would i go about achieving this effect? i tried converting ints to string as in my current program but it doesnt seem to work

There should be nothing wrong with using arrays (or vectors) or images.  Step through your code in the debugger, checking the variables along the way to find where it's doing something you don't expect.

[qsik]

i fixed my image code, but i still cant get GetModuleFileName to work, how do i use it so i can get a string to use? if i use strings, i get errors but i dont know how to turn TCHARS into strings!
