Hi!
I am new in D language. I implement a little 2D/3D engine, and during the development I faced an interesting problem.
I have this function:
void addBackgroundToLayer2(char[] textureName, float posx, float posy)
{
CTexture tex = new CTexture(textureName); //create the texture
tex.m_itexurePosX = posx;
tex.m_itexurePosY = posy;
writefln("X: %f, Y: %f", tex.m_itexurePosX,tex.m_itexurePosY);
m_Layer2~=tex;
}
The problem is that the value of tex.m_itexurePosX variable will be "-nan". But value of posx is good.
If I change the sort of the lines:
void addBackgroundToLayer2(char[] textureName, float posx, float posy)
{
CTexture tex = new CTexture(textureName);
m_Layer2~=tex;
tex.m_itexurePosX = posx;
tex.m_itexurePosY = posy;
writefln("X: %f, Y: %f", tex.m_itexurePosX,tex.m_itexurePosY);
}
Then everything works fine. What do I wrong? I do not understand this problem. I use dmd 1.037 compiler.
