Hello,

I have been trying to get as much information about how features of arc work by looking over the source code, but I have ran into a problem. If what I am assuming is incorrect, please let me know. I understand Texture to ignore attempts to re-load the same file into memory. I have a large 2 dimensional array of sprites (arclib-sprite) and was filling them with the same texture just to have a starting point...sorta like a giant tile map where all the tiles use the same texture. The file used is a 32x32 pixel png image. I figure that it will load the file one time and then coast on by the others really quick. According to the arc.log file, it does seem to be loading the texture only once, but it is taking forever to load. Something like 30+ seconds. When I look at my task manager, it indicates that my memory has now an additional 146-ish MB extra taken up.

A simplified version of the problem is below:

Code:
module test;

import arc.window;
import arc_sprite.sprite;
import tango.io.FileConduit;
      
int main()
{
   ushort i = 0;
   ushort j = 0;

    arc.window.open("Game", 800, 600, true);

    Sprite tiles[][];

   tiles.length = 400;
                  
   for(i=0;i<400;++i)
   {
      tiles[i].length = 300;
   
      for(j=0;j<300;++j)
      {
         tiles[i][j] = new Sprite(COLLISION_TYPE.BOX);
         tiles[i][j].addFrame("img.png", "static", -1, null);
      }
   }
   
   log("done loading");

    arc.window.close();

    return 0;
}
      
void log(char[] msg)
{
   FileConduit file    = new FileConduit("log.txt", FileConduit.WriteAppending);
   file.output.write(msg);
   file.close();
}


After commenting out the line that calls addFrame, it takes about 2 seconds to complete. Why is this taking so long? If this is by my error or misuse, then please feel free to correct me.

Thanks for your time and patience,
Zane

Look at the implementation of addFrame to see how it handles loading the Texture... If it is, in fact, using the static constructor to load the texture then something strange is afoot in the core.
Otherwise, it's something with arc_sprite.

I'll look at it soon, but not at this moment.

Can you send me the image file, too, so I can try to reproduce the error?
