Contraption Maker Update: Dogs & Mods & Bears, Oh My!

After just a couple months of being 1.0, we are super excited to bring you the first major update to Contraption Maker. This update adds new parts, features, puzzles, and even JavaScript mod support. This is completely free, so go update your game and start playing today!

To celebrate this update, we are also running a huge sale on Contraption Maker this week. Contraption Maker is 90% off making it only $1.50 for the 2-key pack! If you have been holding off on getting the game, now is the time to come check it out. Come make some puzzles or contraptions, and join everyone else in our Steam Workshop!

New Parts
  • Tinker: Tinker is the newest addition to Contraption Maker's cast of characters. He loves eating and chasing cats. Attach a leash (rope) to him to control your contraptions in a new way.
  • Dozer: All Dozer wants to do is sleep. Like Steve the Crocodile, Dozer doesn't move. If something falls on his back, they will bounce off of him like a trampoline. Just stay away from his mouth, he will eat anything!
  • Dog House: Tinker's house. Use this as a puzzle goal.
  • Dog Bone: The dog bone will attract Tinker. Tie a rope to it to pull it around. It can be set to 3 different sizes that determine how long Tinker takes to eat it.
  • Dog Toy: Tinker loves to chase these toys.

This update introdues a whole new class of parts called "Tim Parts" that we are really excited about. These parts don't do anything untl they are activated and used by Tim. Tim Parts are going to add a new level of control in contraptions, and there will be more added in future updates.

  • Dog Toy: This dog toy behaves just like the other, but it wont move until Tim picks it up. When he does, he will throw the ball a short distance. If it hits another Tim after being thrown, the new Tim will throw it again.
  • Dog Treat: Once Tim picks up the dog treat, he wont use it until he gets in range of Tinker. Once he sees Tinker, Tim will place the treat on the ground to bring Tinker to him.
  • Dog Whistle: When Tim picks this part up, he uses it immediately. The whistle will attract any dogs in a circle around Tim.

As an extra little added bonus, the egg now has 10 different looks to choose from.

Mod Support
We now have the first version of mod support in the game. Mods are made using JavaScript and can be directly coded and edited in the game. Mods are integrated into the Workshop, so they can be easily shared and played. There are 3 example mods already in the Worklshop, so check them out! Here is a short example video of how the system works:

Check out our WIKI DOCS if you want to get started out!

New Puzzles
10 new official puzzles have been added. These puzzles focus mainly on Tinker and the new parts that have been added along with him.

New Scenery & Music
A new "neighborhood" scenery set and 6 new songs have been added to give more variety to your contraptions and puzzles.

Camera Animation & YouTube Uploading
You can now animate the camera for when you record your contraptions. Open your contraption options and activate the CAT (Camera Animation Tool) to activate the tool. The camera can then be animated just like scenery parts. Official documentation for this will be coming soon.

Once you make your awesome contraption movie, it can now be uploaded directly to youtube. After the movie is done recording, just select the "Upload to YouTube" button to go through the quick initial process. Once your account is linked, the process becomes instant!

Assorted Fixes
  • More thoroughly integrated script collision callback handlers into chipmunk and CMLevel code. Also made how they are tracked and store for the callbacks to the script much more efficient. Added 8 Waldos to the PlatformTim level, gave them all onSensor handlers in script, and then copied and pasted a bunch of walls in front of their sensors and script was only taking roughly 2% of total time profilier.
  • Added a #ifndef check to chipmunk_private.h to keep from being included twice (and causing a boatload of compile errors)
  • Set up some flags so shapes can be marked as sensors in chipmunk but be treated as "onCollision" calls in script
  • Converted a few sensor flagged collision into real flagged collision but didn't change actual behavior.
    Do not call handleCollision if there is no collision callback function
  • Added applyForce to script part proxy to allow force (impluse) to be applied at the passed in angle
  • Added new routines to allow getting and setting of part's rot, setting of part's rot velocity, setting part disabled gravity, setting disabling of creature intelligence, and setting of creature's state
  • Deduping collisions
  • Remove onSensorCollision call
  • Do not redirect stdout/stderr in testcompat mode
  • Changed force value passed into jsAddForce so it is 1000x less powerful to allow smaller forces to be applied. Current forces used should just be scaled up by 1000 and the mods will then run the same.
  • Created a faster rope segment integration method to be used by electrical cords
  • Made number of integrate steps used by dynamic rope segments a var instead of a fixed value
  • Made the high priority repulse distance a var that can be set by different creatures instead of a fixed value
  • Clamped Creature rotations to min/max values - only used by Tinker for now
  • Clean up Fishbowl and Hamster Cage - same behavior but more efficient code
  • Script window comes up too large on small screens
  • Egg contraption states
  • Modified animations to to handle looping animations that have a intro that don't loop
  • Clear console on play, also scroll to bottom when new text
  • Can now scroll console too
  • Handle scroll wheel in the script editor
  • Fixed: Milton's goal state crashes game
  • Republished mod to Steam - it was blank
  • Fixed: :Big grey pipe” part message
  • Misspelling on plug in bulb message
  • Fixed touch activated sound block help
  • Missile now plays blast off sound
  • Fixed: Highlight for spring board is not drawing correctly

Build-Off #1 Results Are In!

Now that we've had all of your submissions for a week, it's time to announce the winners. This took a little longer than expected because you guys definitely didn't make this easy on us! The quality of the submissions was absolutely amazing, and it was very hard to decide on the top 3.

There were a couple of bumps in the road along the way, but this was our very first contest. Things will go smoother and easier as we do more of them. This contest was definitely not some one-off thing. We plan to do these fairly often, so if you didn't win this one you can come back and try again next time!

If you didn't make it into the top three, don't fret. Like I said, this was a super hard decision and I wish you could all be winners. I know that sounds cheesy, but we were seriously blown away by everything you guys submitted :-)

3rd Place: Four Seasons Of Eggtraption, by aztimh
From the beautiful scenery, to the poem in the description, this is a super cohesive contraption. This is one of those contraptions that you need to watch a few times to really catch everything that's going on.

2nd Place: Egg Coloring, by Scott
This contraption really pushes the egg to its absolute limit. Bouncing off of toast, getting hit by a swinging bucket, landing on top of a rocket, so many things in this contraption make you say "wow!"

The finale is what really puts it over the top. What looks like a boring grey contraption comes to life with a great scenery animation that pulls everything together.

1st Place: Eggcity, by Thesandwichcake
Eggcity is unlike anything we have ever seen created in this game. Thesandiwchcake came at this in such a crazy creative way. The contraption really is a little city. There is a bar, eggs going to school, eggs gambling with each other, and eggs driving cars.

There are so many fun little details scattered around the scene. Add to this a crazy awesome laser system powering the whole thing, and you've got yourself our first place winner!

There you have it folks, our first build-off contest is in the books. Wait just a few short weeks and we will be having our second contest with a new theme! I'm real excited to see what awesome stuff you guys make next time!

“This is a cool game that really tests your imagination.”

“It is a from-the-ground-up modernization, with enough familiar elements to instantly excite old fans of The Incredible Machine and enough modern touches to fuel the imaginations of gamers who have never touched the original.”

The puzzles seem a bit simple so far. As a player of the incredible machine, however, it's still well worth the full price of $15. BUY IT AND PLAY IT NOW!

Steam workshop support means that even after the game is complete/released, the community can continue to create puzzles.

I only hope they add some more parts for us. I don't usually say this, but even a series of cheap (read: $1) DLCs would be welcome here, with more parts and puzzles after the game is released. A limited number of parts means a limited amount of replayability.

Early Access Review
I remember playing The Incredible Machines in my school days. I really enjoyed the game back then and I always wondered why there are no modern games like that. Well, now there is Contraption Maker. Only now it's my 6 years old son who has spent more than hundred hours playing it and will surely spend much more.

This game offers exactly what that old classic offered - you can solve pre-designed puzzles or create your own. Since this is not the finished product, there are not too many pre-desined puzzles, although more are being added as the time goes. The creation part however is already a lot of fun.

Conclusion: this game is well made and I trust it to become even better as development continues. My son loves it and I respect it for helping develop his creativity and problem-solving in a fun way.

Early Access Review
I'm writing this review during Early Access so this could change as development goes on:

Highly addictive game play for the Rube Goldberg enthusiast.

I started out on medium and I clicked through most of the suggestions/tool tips. The game is not intuitive. So you will want to start off on easy and learn your way to medium.

You will discover there is more than one solutions to each task. The best part is you can save a compressed version of "your" solution right from the game. It will save it to your hard drive for later access or if you would like to share it with friends later. Can do and did. Also, you can check out the "developers" solution to compare after you have completed a puzzle.

The graphics are kind of...elementary...but the game play more than makes up for it.

This is a very fun game, and it definetly reminds me of the Incredible Machine series. Thanks a bunch, developers! You're doing a great job bringing the series to the modern age.

The classic The Incredible Machine game is getting a reboot!

Contraption Maker is played exactly similar to the TIM series. You solve a puzzle by placing certain parts in the work area and try to do things such as popping a balloon, getting a person or mouse home, or even completing a large list of objectives involving cooking appliances.

Did some official puzzles and know how the game works? Great, now you can create your own puzzles or automatically solving contraptions for the whole Steam Community to see.

Anyone who was a fan of the orginal TIM games will certain enjoy this reboot. Even though the pyhsics aren't the same and most parts have a redesign.

This game will for certain bring back those wonderful memories of having Mel being eaten by Edison Crocodile. *Edison's snicker*
