drawcross / drawline

Drawcross used to show locations of world_items in Half-Life: Source.

Drawline used to show it's white when LOS is not blocked and otherwise red

drawcross and drawline are console commands available in all Source games. Creates lines or crosses. Cross consists of 4 lines and there are 20 lines possible to be drawn at once (i.e. 5 crosses, or 4 crosses and 4 lines, 3 crosses and 8 lines etc.). The lines they draw are red if intersecting with something that blocks line of sight otherwise white.

Tip:clear_debug_overlays command doesn't clear these lines but it's possible to hide them by issuing drawline 20 times. It's possible to alias it as follows for quick way to clear them. clear_debug_overlays is autocomplete by console and adding 2 at the end is fast.

alias e drawline;
alias clear_debug_overlays2 "e;e;e;e;e;e;e;e;e;e;e;e;e;e;e;e;e;e;e;e"
