A wide variety of puzzles to solve

Hey everyone! We\'re pleased to announce that Trick-or-Treat Adventure just \"went live\" on Steam!\n\nWe\'ve been working hard to refine and polish the story, code, and animations while adding new content for the launch plus make sure all the bugs are squashed while testing across Window, Mac, and Linux/Steam Deck.\n\nWe finally feel that it\'s ready for prime time!\n\nWe love Halloween and retro point-and-click adventures, and this is a great fusion of the two. We\'ve poured our hearts and souls into this game and can\'t wait for you to experience it.\n
No spoilers, but if you enjoyed Abobo\'s Big Adventure (which we also made) or are a Horror movie afficionado, or a fan of classic adventure games like Day of The Tentacle, Sam & Max, Monkey Island, Grim Fandango, and Full Throttle - you\'ll love Trick-or-Treat Adventure!\n\nHuge thanks to everyone who has supported us along the way, special shout out to Newgrounds and Tom Fulp for sponsoring the original web game in 2007 that was the foundation for this huge Steam upgrade.\n\nThanks for playing and may your Halloween be filled with ALL THE CANDIES!\n\n-- Team TTA

Weekly [u]Trick or Treat Adventure[/u] for Steam update time!
(don\'t forget to [u]wishlist![/u] )
Add \"quality of life/user experience\" enhancements (pathfinding, bug fixes, menu stuff, etc.)
Get it working on Windows, Mac, Linux, and Steam Deck
New content ???
We\'ve turned a corner on development and are working on adding NEW content to the game! (You thought you could keep the developers of [u]Abobo\'s Big Adventure[/u] from scope creeping???)
The first item of business is making \"combining inventory items\" more exciting. We\'re hoping this feels special for the player (an encouraging reward/payoff for solving puzzles) and provides some nice visuals for an upcoming new video trailer.
Check it out!

Currently, there are around a dozen different inventory item combos you can do... that might grow though!
We have some cool ideas for more new content too!
Come back next week to see what the next big idea is!
Any guesses?
And once again... [u]WISHLIST ON STEAM![/u]

In my efforts to post a [u]Trick or Treat Adventure [/u] update every week, here is a more technical deep-dive into one of the improvements for the Steam release...
[u]PATH FINDING![/u]
In the original web version of the game, it was pretty frustrating to get around because you would run into \"non-walkable\" areas all the time and there was no logic to smartly navigate your character around a room. And if you clicked something interactive, but weren\'t close enough or lucky enough to be able to walk right up to it, you\'d get an annoying message telling you to get closer.
[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45705236/7474facb561f867aedb010da97adad85604a3af5.gif\"][/img]
In the new version, we\'ve implemented better path finding! You might be thinking: \"Wow, you must have used some advanced pathfinding algorithm like A*!\" But you\'d be wrong... DEAD WRONG!
The way we did it is actually based on an old post by Aaron Worral about how he did pathfinding in [u]Johnny Rocketfingers 2 [/u]! Basically, you put down (as named MovieClips) some \"numbered nodes\" in strategic walkable areas of the \"room.\" These nodes can all \"see\" each other (direct line of sight) without running into non-walkable space. They\'re numbered, so they form a kind of \"ordered backbone\" to the walkable area of the room. You only need enough nodes such that every walkable area of the room can be seen by at least one node without hitting the non-walkable area.
[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45705236/8608e91843a760583e5445ce0105ea7151353b08.jpg\"][/img]
Here they are overlaid on the kitchen background/room from the game. The transparent red is the \"antiwalk\" (non walkable) area of the room. You can see how it feels like the room\'s \"spinal cord\" and each vertebrae can allow access to areas of the room it can see directly (direct line of sight).
[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45705236/3ebd441e8954b83f3c7c1721b63f823f8c57d4e5.jpg\"][/img]
Then the rest of the logic is pretty simple:
[olist]On a click, can the player reach the destination without hitting antiwalk? Just go directly there.
[/*]Is the destination blocked? Ok, get the node nearest the player and the node nearest the destination. Figure out if the node nearest the destination is greater than or less than the node nearest the player (this tells you which direction on the spine you need to move). Move the player to the spine node nearest him.
[/*]Navigate along the spine (either increasing or decreasing node number based on step 2 above).
[/*]You can either wait \'til you reach the node nearest the destination and then walk to destination, OR you can just constantly check if the destination is \"in direct line of sight\" with the player, and as soon as it is, walk to the destination.
[/*][/olist]It\'s really that simple! Of course you need to write some code that uses a while loop to do the direct line of sight checking (using trigonometry to crawl along the hypotenuse of a triangle in small increments to see if you hit the antiwalk at any point). That\'s probably the most \"complex\" part, but you can do it!
The code might look something like this (wow Actionscript 2.0!!!):
[code]// determines if player x,y has a direct line of sight to a destination point\n// without hitting the antiwalk\n// allDots = \\[] // uncomment this to visualize what this code is doing\nfunction hasDirectLineOfSight(x, y, who) {\nvar distx = x - who._x;\nvar disty = y - who._y;\n\n// hypotenuse of the triangle!\nvar hyp = Math.sqrt(distx * distx + disty * disty);\n\nvar dx = distx / hyp; // 1px increment in desired direction for x\nvar dy = disty / hyp; // 1px increment in desired direction for y\n\nvar startx = who._x;\nvar starty = who._y;\n\nfor (var i = 0; i < hyp; i += 6) {\nstartx += dx * 6;\nstarty += dy * 6;\n\n/*\n// use this if you want to actually visualize what this code is doing...\nvar d = wrap.attachMovie(\"vtest\", \"vtest\" + i, i + 8888);\nd._x = startx;\nd._y = starty;\nallDots.push(d);\n*/\n\n// checking if we\'re hitting the antiwalk\nif (wrap.aw.hitTest(startx + wrap._x, starty + wrap._y, true)) {\n//trace(\"hit antiwalk!\");\nreturn false;\n}\n}\n\n//trace(\"clear!\");\nreturn true;\n}\n[/code]Hopefully that made sense!
Here\'s the final result, sooooo much nicer to play now!

Are you ready to point-and-click your way through a ridiculous, spooky, pixelated adventure? You better be, because our retro-style Trick-Or-Treat Adventure game is coming to Steam October 1st, 2025!
Trick-or-Treat Adventure hearkens back to the the classic adventure games we grew up on from the likes of LucasArts and Sierra back in the day. You'll take control of Little Johnny, a neglected outcast who simply wants to slap together a cheap, makeshift Halloween costume out of household items so he can go trick-or-treating in his neighborhood. But trick-or-treating in this twisted town isn't as simple as ringing a doorbell and asking for candy.
No, you have to earn your candy here. What does that mean? Maybe you'll have to sacrifice an innocent... maybe you'll have to venture into the sewers... maybe you'll have to battle the forces of darkness. But hey... it's all worth it because... CANDY!
We've made a boatload of upgrades including improved pathfinding, an updated script, and many more unique interactions! The game features numerous Steam achievements, cloud saves, and will be available for PC, Mac, & Linux players!
Add the game to your Wishlist and mark your calendars for October 1st so you can be among the first to go on a Trick-Or-Treat Adventure!
