title: Unity: Make a tile take up more grid cells
body: <p>I am trying to create a basic tower defense game where I have set up my cell size to be 0.5 X and 0.5 Y (so that the player can place their towers more freely, think WC3).</p>
  
  <p>This causes problems when I later in the game wants to check if a grid cell is occupied, because some cells will seem to be taken, but actually are not.</p>
  
  <p>Here's an image to illustrate my problem:</p>

  <p>The black square is rendered over 4 cells, but only 1 of the cells are occupied (the white square in the lower left corner of the black square).</p>
  
  <p>Have anyone else faced this particular problem and knows how to solve this or are there any other solutions that you would like to recommend? :)</p>
  
  <p>Thanks in advance!</p>
