Created: Wed, Jan 11, 2017 10:12 AM


VEX STACKUP- Is a 3D Animated game based on scoring balls and tetrahedrons on 3 posts.

Standard VRC rules apply, such as field dimensions.

The game will be played by 2 teams in each alliance, and there will be 2 alliances in the game. This design was meant to be competitive for any participants and can be used in the real world and will not defy any laws of physics.

This entry was submitted by a new team in this online game design challenge, and our goal was to surpass and achieve the greatest graphics and video editing techniques and bring competition to the participants. Although specialized in Autodesk softwares such as Autodesk Inventor, we chose to go out of the comfort zone and do this animation on Blender. Our biggest efforts have been put together in this video for the judges and viewers to enjoy and inspire.

We hope you enjoy our Game, thank you!

Huge thanks to NoCopyrightSounds for the music!

@steamworks you would be right. However it says "The Challenge Objects are part of the challenge to introduce a real-world limitation. Like any other engineering problem there are constraints, and in this contest the Challenge Object is one of your constraints." meaning that they can't use any other objects. So clearly this is wrong.

Of the 3 entries I spent time providing significant feedback on this was the only one with non-specified challenge objects. Balls are a whole lot easier to create and dynamically animate which is perhaps why they weren't included in the constraints? Maybe using balls may count against it but to what degree is unknowable. "The game must incorporate at least one of the challenge objects described below, and the challenge object(s) used must be significantly involved in the scoring of the game." This requirement suggests other types of challenge object could be used for scoring with specified challenge object(s) only being significant to scoring and not necessarily 100% of scoring.

It was a good video, but still "Failure to fulfill any of these requirements may result in your entry being disqualified from advancing to Finalist or Winner status." And you guys did the challenge object part wrong, so...

I love the cinematography in this video

@zjushenc is right. You guys did violate the rules. "The Challenge Objects are part of the challenge to introduce a real-world limitation. Like any other engineering problem there are constraints, and in this contest the Challenge Object is one of your constraints..." This would mean that you are only allowed to use the three that they provide you with. It says you have to use at least one meaning you would only have the one you chose in your game because there are no other objects they allow you to use because you are constrained and limited in objects. @EastwoodRobotics

@steamworks Thank you for the feedback, I'll be taking everything into account for next year's competition! This is our first year entering the VRC game animation challenge. @zjushenc I understand your viewpoint,but if you read the rules it clearly states that at least 1 of the game constraints (objects) has to be from the list mentioned,which included the hoop, the sea urchin, and the tetrahedron. In our game we incorporated the tetrahedron so we do not violate any rules since we are using one of the game constraints.

   zjushenc on 01/26/2017

I'm agree with what steamworks said. One thing that bothers me the most is, why you guys used balls rather than urchins. Cause among the three scoring objects , there is no balls. So I'm afraid this is a violation against the rules though.

This is one of 3 entries which obviously had loads of time and effort from the team and deserve lots of constructive feedback. The game explanation and demonstration flow together really nicely with good narration although it is occasionally drowned out by the music. The lack of any kind of background or floor makes the animation environment seem less realistic than it would be otherwise. A realistic field perimeter and tiles which interlock together properly – nicely done. In the game explanation it really looks like those tables were thrown in there at the last minute since at one point it actually floats above the field and then the 25 point on-table scoring animation just looks really bad. Everything else looks nice, but that doesn’t. That said at least we could re-use the table field element post season so that’s a bonus! Great use of depth of field but there’s at least 1 time the primary focal point isn’t actually in focus so make sure the views look right. Also having a really short dof can be unrealistic since us humans wouldn’t actually see it like that. Good use of texture on the balls although it looks like marble which is a little odd since any kind of real plastic or foam ball wouldn’t look like this at all. The dynamic motion of balls is pretty good. Can’t figure out why one corner of the tetrahedron is pointy? Also you’d need field resetters with skinny 4’ long arms who can reach down the center tube and adequately securing those 2’ long horizontal bars could be tricky. Quite like the way balls scored in the middle post can flip color depending on tetrahedrons scored but it might sway the match a bit too much making a last second middle post tetrahedron descore a likely strategy and being able to just slide them all off makes that too easy. The robots look pretty realistic and wheels mostly move correctly with motion but there’s nothing holding them together and the gears don’t actually play any part in the arms which seem to direct drive from motors. Also you seem to have invented a new kind of drive system the X-H drive! Some additional finishing touches would really help along with alliance color plates so the demo match is easier to follow. When you slow down the amination to 0.25x speed there are many obvious object penetrations between balls, tetrahedrons, robots, claws and scoring posts. There are also some odd little position blips just as some action takes place with an object. Don’t really like the claw shooting a ball since that just doesn’t happen. Hope that feedback is useful and make sure you enter again next season! Good luck!

There's a lot of little detail here. I'm sure this entry will win, great use of DOF. A couple of areas had messed up smoothing groups, but that's nothing to cry over. I was particularly impressed with the work you guys did on the tiles, I know from first hand experience how hard it can be to get those right.

Probably my favorite submission so far
