 === Description ===
+Assigns a directional field on a specified cell. Only one field can exist on a cell - changing a field again will fully override the previous field.
+VectorUp and VectorRight control the direction of the field. For example, values of:
+  * 1 1 will create a field that points in the upper right.
+  * 1 0 will create a field that points up.
+  * -5 0 will create a stronger field that points down.
 === Examples ===
-<code>	f2 = GetFloatFromStack(); //force y
+Spawn a weak field that points right at coordinates 5,5.
-	f1 = GetFloatFromStack(); //force x
+<code>
-	i2 = GetIntFromStack(); //y
+5 0.0 1.0 SetFieldCell
-	i1 = GetIntFromStack(); //x
+</code>
+Spawn some fields in a radius under a unit.
