I'm trying to make a collision test on a custom entity  that changes the hero animation while overlapping. Setting the animation works, but the animation persists outside of the entity until the hero stops moving. What do I do to fix this?

This is the chunk:

Code ( lua) Select Expand

  entity:add_collision_test("overlapping", function()
    if entity:overlaps(hero) then
      hero:set_animation("spring")
    end
    return true
  end)

Hey, I started working on the dialog box for the level up system, and it is supposed to show a dialog that allows you to pick a stat to boost, but if a stat is maxed out, it will show a dialog allowing to boost the other two, and if two are maxed out, it should boost the last stat. I've tried multiple different things, and it continues to just show the same dialog, so I decided it might be easier to ask on the forums.

This is the chunk of code:

Code ( lua) Select Expand

self.game:set_value("current_level", current_level + 1)
difference = current_xp - xp_to_levelup

current_xp = self.game:get_value("current_xp")
self.current_xp_displayed = 0
self.current_xp_displayed_length = string.len(self.current_xp_displayed)
    self.game:start_dialog("levelup", current_level + 1, function()

Hey, I've just started to try and implement @froggy77 's level and xp system. However, his system is based around zelda roth and my game is based around zsdx code.

http://forum.solarus-games.org/index.php/topic,520.0.html

I believe the problem is declaring new savegame values, however nothing I've tried seems to work. I tried changing everything to roth, but that turned out to be a lot more trouble than I expected. I tried putting the values at the end of the savegames code and that didn't seem to do anything. Where should initial values be saved in zsdx?

Hey, I'm continuing to work on items and just had 2 questions regarding what is possible.

1) For a gust type spell, is it possible for the amount of pushback to be changed/doubled, or is the pushback static

2) Can there be an item like the magic ring from ALTTP that can half the amount of magic needed to cast spells?

Hey I'm currently working on the map for one of the final dungeons in my game. My plan is to create a portal gun type item that shoots entities that can create teletransporters when they collide with a special portal wall. Before I design the entire dungeon around this item I was wondering if such a thing is even doable 

I'm trying to make a vine entity that can only be destroyed by using fire. There's no error, but the entity doesn't get destroyed when fire is used.

Code ( lua) Select Expand

local entity = ...
local map = entity:get_map()

function entity:on_created()
  self:set_size(16, 16)
  self:set_traversable_by("hero", false)
  self:create_sprite("entities/bush_vine")

    if entity:get_type() == "fire" then
      sol.audio.play_sound("jump")
      self:remove()
   end
end

function entity:on_removed()
  self:get_sprite():set_animation("destroy")
end

Hey, I'm planning to implement a crafting system that involves talking to NPCs and they will show a selection of craftables and the regents required to make them. I figured it would be easier to make this as a dialog that displays craftables and checks if you have the regents when you select it. Is it possible to have more than 4 selection in a dialog that you can scroll through or would I have to create a menu for a crafting system to be possible

Hello everyone, I've been steadily working on my project and am currently making graphics for NPCs. I figured since everyone in the forums have been so helpful that if you want, I can draw in an avatar or whatever you want as an NPC in the game. If anyone is interested, write here or shoot me a PM about a general idea of what you want the NPC to look like and what you want the NPC to say/do. 

I've been working on dungeon design,and have been using the door_manager code. I'm having a couple probelms, but with that code, one door will open when one auto_enemy is killed and the rest will open after the others are killed.

And in the code of one map:

Code ( lua) Select Expand

local map = ...
local game = map:get_game()

local door_manager = require("maps/lib/door_manager")
door_manager:manage_map(map)

function map:on_started()
  function map:on_started()
  if not game:get_value("dun1keyy") then chest_key:set_enabled(false) end
end

  map:set_doors_open("auto_door_f", true)


  self.night_overlay = sol.surface.create()  -- Create an empty surface of the size of the screen.
  self.night_overlay:set_opacity(152)        -- Make it semi-transparent (0: transparent, 255: opaque).
  self.night_overlay:fill_color({195, 24, 24})  -- Fill it with dark blue to obtain a night effect.
end
function map:on_draw(destination_surface)
  self.night_overlay:draw(destination_surface)
end

function bridge_switch:on_activated()

  sol.audio.play_sound("secret")
  map:set_entities_enabled("bridge_tile", true)
end

function close_auto_door_f_sensor_1:on_activated()

  if auto_door_f:is_open()
      and map:has_entities("auto_enemy_auto_door_f") then
    map:close_doors("auto_door_f")
  end
end

for enemies in map:get_entities("auto_enemy_auto_door_f") do
  enemies.on_dead = function()
    if not map:has_entities("auto_enemy_auto_door_f") and not game:get_value("dun1keyy") then
      chest_key:set_enabled(true)
      sol.audio.play_sound("chest_appears")
    end
  end
end

the auto_door_f wont reopen after the enemies are killed and the chest_key doesn't start out false

Would there be a  way to code a horse like Epona that the hero would be able to ride? And would it be considered a custom entity or some sort of NPC

For my game, I want to create a leveling system that is a mix of ideas between Zelda 2 and Skyrim. Every time you reach a new level you can choose to raise either health, magic, or stamina with a max level of 10 for each, making a maximum total level of 30.

First off, is such a system possible with the engine. Second, if it is how would I get started creating it?

Hey, I was working on making crystal/crystal block sprites for dungeons. Is there a way for every dungeon to have a different sprite for crystals rather than all of them using the same ones?

I noticed while looking through the zsdx and roth repositories that there were no bomb or bow soldiers. Is it possible to make an enemy that throws bombs?

I'm not too sure about how to go about making turrets that remain stationary but continuously fire(I supposed using a timer)

One turret would fire in one direction but does not change direction to follow the hero, one fires in four main directions(N,S,E,W) and another that fires in eight direction (N,NW,NE,W,E,SW,SE,S)

Hey, I would like to try to create an item similar to the Lens of Truth from OoT, and I would just like to make sure something like that is possible. My initial thought process is to make the item enable specific dynamic tiles while it is being used and then re-disable them when the item is no longer in use.

Hey I'm having a bit of trouble with arrow switches. 1)When I shoot an arrow, the arrow goes straight through the switch rather than activating it. 2) Is it possible to require more than one switch in order to activate a dynamic tile like a bridge?

Hey so I was trying to make a custom entity that restores health over time. The code basically works fine but the timer covers the entire map rather than just when traversing the entity. Is there a way to make it so the hero has to be on the entity for the timer to activate?

Also, how do i change the hero animation on the entity because set_animation doesnt seem to be working...

I just got a new laptop and I tried to move the data to it, but now the screen is black and I am receiving an error that did not exist on my original computer.

"Error: In timer callback: [string "scripts/menus/title.lua"]:27: attempt to index local 'zs_presents_img' (a nil value)"

I had this error before, but it was fixed so I'm not sure why it is suddenly reappearing when I have double checked that the image required exists under languages

In game manager I keep getting an error towards the hud: "Error: In on_map_changed: [string "scripts/game_manager.lua"]:75: attempt to index upvalue 'hud' (a nil value)"

and the dialog box creates the error:  Error: In on_started: "[string "scripts/dialog_box.lua"]:59: attempt to call field 'get_dialog_font' (a nil value)"

Clearly the problem is about the nil values but when I try defining either of them the error remains so I'm not quite understanding what to do....

Is it possible for the hearts and magic bar used in ZSDX to be instead shown as red and blue orbs like in Diablo? I tried to simply use the code and custom graphics but I'm not exactly sure how to compile the graphics to create a HUD.
