Tile movement check

Hi all,

I am after some thoughts on grid based movement (for a chess style game). If you look at the attachment I have a setup of 3X3 ray sensors area around a unit which checks the properties of the grid tiles. If the right conditions are met it will send a message to highlight the appropriate tiles so the player knows which tiles can be moved to.

This works fine, but it seems a bit messy and not that flexible (I’ll probably need a different array for each type of unit). I was wondering if anyone has any ideas of other ways this could be achieved?

Thanks,
Blenderage

Simple solution

tileList = [[‘blue’,[0,0,0]],[‘blue’,[1,0,0]],[‘blue’,[0,1,0]],[‘blue’,[1,1,0]]]

If you set the tiles to be 1x1 blender units and name the like ‘tile_x_y’ where x is the x position and y is the y position you can use the location of the object you are checking to find tiles.
e.g.

object = obl['OBCube']
[x,y,z] = object.getPosition()

middle_tile = obl['OBtile_' + str(x) + '_' + str(y)]
above_tile = obl['OBtile_' + str(x) + '_' + str(y+1)]
below_tile = obl['OBtile_' + str(x) + '_' + str(y-1)]
right_tile = obl['OBtile_' + str(x+1) + '_' + str(y)]
left_tile = obl['OBtile_' + str(x-1) + '_' + str(y)]

You will have to be careful because if the object is on the edge then it won’t be able to find some tiles because they don’t exist.
