# How to add PDA markers Files & folders needed: > assets/gameplay/pda.json > > assets/ui/pda/ > > assets/scripts/p\_game.gd Map size is **568x832**, where **0x0** is top left corner of the map. Here is JSON structure of marker: {% code title="pda.json" %} ```json "garbage_camp_marker": { "name": "quest.trus.0.name", "spot": "area_neutral.png", "type": "camp", "position": [384,388], "level_id": "garbage_camp" } ``` {% endcode %} {% code title="Properties description" %} ```ini garbage_camp_marker = Unique ID for spawning with scripts name = string or language key from lang_*.json file spot = marker icon file name relative to assets/ui/pda/ folder type = "camp" for safe levels, "quest" for combat levels position = [X, Y] position of the marker on the map (maximum [568, 832]) level_id = name of the folder/file of the level in assets/levels/ that will load ``` {% endcode %} {% code title="pda.json" %} ```json "my_mod_level": { "name": "My mod new marker", "spot": "marker.png", "type": "camp", "position": [135,28], "level_id": "garbage_camp" } ``` {% endcode %} Create new marker structure at the end of the file, use spot icon from assets/ui/pda/marker.png

Then to add this marker, open assets/scripts/p\_game.gd and add this marker to the player PDA. Using this function: ```gdscript pda.AddMarker("my_mod_level") ``` Also you can check if marker exist at the map and delete it: ```gdscript if pda.GetMarker("my_mod_level"): pda.DeleteMarker("my_mod_level") ``` Don't forget that you need show PDA (enable pda button in menu and on keys M or P on keyboard): ```gdscript GameManager.ShowPDA(true) # false for disabling ``` After adding marker with any method, by event key or completed quest, or changed level, check PDA.
