update v0.6 Adds exact measurements for things that are not radial burst (which are most AOE effects in general as they expand from an intersection point). It will snap the center of the intersection to the upper left most corner of the 1x1 unit graphic. Uses the same exact syntax. !growit -exact update v0.55 Removed unrelated dead logic. Grows an AOE graphic that's 1 unit in size, to the desired radius (excluding the center square); centered at the origin. It also moves the graphic to the map layer as a bonus. Useful macros to use this easily: grow
!growit ?{radius(ft)}
grow-exact
