Hi, I'm fairly new to D and I'm writing a Space Invaders clone to get myself
acquainted with the language.
I'm having trouble passing D strings (char[]) to SDL, in particular
SDL_LoadBMP(), I keep receiving a segfault.
Heres the code:
void setImg(string path) {
// concat null terminating
Use toStringz from std.string, ala:
SDL_LoadBMP(toStringz(path));
Do not embed nulls before calling toStringz, so remove 'path ~= \0;'
Wait, actually I'm not sure if there's toStringz for D1, it is there
for D2. Try it out, I guess.
toStringz is in D1 but still no luck, I still get the same error
Thanks for the suggestion though
