What I found so far, please add anything that could simplify scripters life and is not in erm help actually.
;If OB:T = 34 (hero). #get object under hero / erm snippet
;Fix day of, all erm help is wrong about:
; redraw town screen
;change battlefield during battle
;Mop function, find hero portrait for DL
;safe functions equip/delete artifact
;set scouting radius
;65000 objects allowed (XXL maps)
;pitlords summon horned demons
;DL addition:
Code:
A#1/#2/$/1 Change dialogue item characteristic.
#1 - item ID
#2 type $
3 Text (string): new text of the item
4 Def (number): new cadre in Def
11 Pcx (string): new picture
#4 parameter should always be 1 (anyone care to explain why?)
Notes:
May be called in !?DL trigger and so may be used to customize the dialog on a fly.
