Dlang and curly brace language noob here. I'm trying to work with the
raylib-d library. I downloaded raylib-d using dub, and I installed
raylib with my package manager on Manjaro. I'm getting a mismatch in
the arguments I'm passing to LoadTexture.
source/app.d(7,32): Error: function raylib.LoadTexture(const(char)*
fileName) is not callable using argument types (string)
In the raylib-d docs/cheatsheet it says LoadTexture uses a string as an
argument.The original raylib docs/cheatsheet says it's a const(char)*
value. So it seems I'm using the C version instead of the D version? The
relevant section of the code below is
import raylib;
void main()
{
InitWindow(800, 600, "Hello, Raylib-D!");
string fname = "assets/tile_022.png";
Texture2D player = LoadTexture(fname);
raylib-d does not have D wrappers for everything. You are supposed to
use the C functions.
D's string literals are null-terminated. However, the language only
allows actual literals to be implicitly converted to immutable(char)* as
literals, not as general strings.
So this will work:
Texture2D player = LoadTexture("assets/tile_022.png");
And this will work too (because string literals are null terminated):
string fname = "assets/tile_022.png";
Texture2D player = LoadTexture(fname.ptr);
If you have a string that you aren't sure is a string literal, you can
use std.string.toStringz to convert it, but this will allocate another
string (possibly).
import std.string;
Texture2D player = LoadTexture(fname.toStringz);
