Actually, I am wrong. (Or even more wrong.) With less than full hearts, the heart script still calls for dialog:"already_have" and won't sell a heart. Hmm...

Development / get amount

« on: February 19, 2018, 04:16:29 AM »

Hi guys! I am making a shop, with NPCs for the items. The map script for the small heart works great for now.

Code: ( lua) [Select]

function shop_heart:on_interaction()

 if        game:get_life(max)
 then   game:start_dialog("already_have")
           sol.audio.play_sound("bounce")

 elseif   game:get_money() < 10 then
           game:start_dialog("cant_buy")
           sol.audio.play_sound("bounce")

 else     game:start_dialog("empty" , function()
           hero:start_treasure("heart" , 1)
           game:remove_money(10)
      end)
end
end
but I am not sure how to properly use syntax to get the amount of the arrows item (the first "if" line).

Code: ( lua) [Select]

function shop_arrows:on_interaction()
   
  if  item:get_amount("arrow" , 30)
    then game:start_dialog("already_have")

    elseif game:get_money() < 80 then
      game:start_dialog("cant_buy")
      sol.audio.play_sound("bounce")

    else  game:start_dialog("empty" , function()
          hero:start_treasure("arrow" , 3)
          game:remove_money(80)
      end)
end
end
Thanks so much.

Development / NPC Dialogue

Hello, I am trying to replicate Solarus Tutorial [en] - Basics #18: Dialogs with a non-playing characteracter https://www.youtube.com/watch?v=KyF4LB1YOSY&list=PLzJ4jb-Y0ufxwkj7IlfURcvCxaDCSecJY&index=18 and for some reason, it is just not working. I am a real beginner so thanks for any help. Here is three screenshots.

Development / World Location, & Separators

« on: February 08, 2018, 04:48:17 AM »

Hello,

I am curious as to how important setting the world location is. For example if there were three standard screens in a world scrolling left to right, you may set them at 0, 320, and 640. Or not. When layering multiple floors (say, replicating the tower with the Moldorm) this seems very important. But otherwise?

Also, what are the advantages/hazards of using separators instead of multiple screens?

Thanks for any insight.
