Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

modified TArray

Hello everyone,

I want to build a modified version of the TArray. I know that I only need a maximum of 250 objects per TArray which i have got 1.000 per container. I am accessing them like this:

 uint8 index[40][40][40];
 TArray<object> data[10][10][10];
 object& GetData(int8 x, int8 y, int8 z)
     int8 ix = floor(x / 4);
     int8 iy = floor(y / 4);
     int8 iz = floor(z / 4);

  return data[ix][iy][iz][index[x][y][z]];
  1. I want my short TArrays to have arrayNum and arrayMax changed to uint8 type (I don't need 4 bytes per value). This is the easy part. But do I have to pay attention to something else if I do so? Does it affect memory allocation in some way or will the unsigned type cause problems?

  2. I need a uint8-TArray value in the uint8-TArray, to store indices of "removed" objects or better the indices of objects that can bo overwritten. If I remove them completely out of memory, I would habe to change the indices in the static array which is no fun.

  3. To prevent an endless loop of uint8-TArrays creating itself again and again I will need one vesion with and one without uint8-TArray in it. The one with contains the one without.

I do not want to know if it makes sense but how it's done. I am struggling most with line 24 to 262 of array.h. I am not getting quiet through this and wondering if I can remove this in my modified copy and include "array.h" instead.

Thanks for your help
