The body of your if statement ("if(GUI.Button(...))") will only be executed one time when you press the button. You can't draw your buttons inside the if-statement. Unity uses an immediate mode for the GUI elements. You have to execute your GUI elements every frame, so they have to be directly in OnGUI:
var Textures : Object[] = null;
function LoadTextures()
{
Textures = Resources.LoadAll("Textures",Texture2D);
}
funtion OnGUI()
{
if(GUI.Button(Rect(Screen.width-177,0,175,30),"Textures"))
{
LoadTextures();
}
if (Textures != null) // When the textures are loaded
{
for (var i in Textures)
{
GUI.Button(Rect(Screen.width/2,Screen.height/2,100,100),i as Texture2D);
}
}
}
Note: Your GUI.Buttons inside your for loop are all at the exact same position, so they all overlap. Keep in mind to give them unique positions. You can also use GUILayout
