|
||||||||||||||||||||||||||||
Now we get into the fun and more advanced gameplay elements. After the following tutorial you will be able to add infected to our map, set up navigational meshes and shoot some infected.
You have to compile your map and be in-game while editing navigational meshes.
L4D Mapping: Navigational Meshes and Spawning Infected - Video Tutorial
Navigational Meshes Console commands:
nav_edit 1: turns on navigational editing
nav_edit 0: turns off navigational editing
director_stop: stops the director from spawning infected
director_start: forces the director to spawn infected
nb_delete_all: removes the survivors and all the infected from your map
nav_mark_walkable
nav_generate_incremental
nav_clear_selected_set: clear a selection
nav_toggle_in_selected_set: select a set that your mouse is pointing at
nav_delete: deletes selected navigation
nav_save: saves your navigation into a file along with your map name .nav
nav_analyze: analyze your navigation for errors
mark PLAYER_START: marks a specific location on navigation with Player Start property
mark FINALE: marks a specific location on navigation with Finale
These two elements are required to make sure that info_director works properly and the survivors know where to go.

What does, "mark THREAT" do?

When I use nav_generate, some locations (roofs) are not generated, have to
place navigation manually.
Have a questions: – Is it better to place navigation manually, or just using nav_generate? – What is difference between nav_generate and nav_generate_incremental?

Yes if the vertical distance is less than or equal to 128 units then the
nav mesh will take care of jumping and hanging on to ledges etc.

Great tut! I thought it was a lot more complicated than this. Turns out
it's really easy!

Thanks Keith and Ian.
Ian: for the most part, yes, but there is tweaking that will need to be done.

This is looking really good

Great set of tutorials yet again - much easier to comprehend when watching
someone doing something than simply reading about it. Do these steps allow
the infected to jump as well (up ladders, over walls etc.) ?
