costmap_subscript/addingsubscribertocu_29.txt | I tried making a separate regular node that I could set as a shared pointer
within my costmap layer which also didn't work. This was due to the plugin not
even recognizing the node I had made within my code. | |
costmap_subscript/3017_82.txt | I would indeed, I haven't looked in excessive detail how this works exactly,
but the concept seems good to me to have in Nav2 and would be actually very
convenient for testing purposes (mainly). Curious though for a more production
reason what you might be doing with this? | |

costmap_subscript/3017_523.txt | But what are the specific mechanics at which you'd make transparency? I don't
think its possible with the information you have available. You don't know
what value of cost 0-255 would remap to "do nothing". 0 could be 0% speed or 0
could be trigger the binary filter -- we simply cannot know. | |

costmap_subscript/3017_495.txt | Initially, I thought about making some kind of "holes" inside vector objects,
and filling them with ` FREE_SPACE ` values, allowing to underlying objects
with lower priority to be on the resulting map.
The example depicted below could not be drawn only by utilizing only ` use_max
` and ` priority ` values:
