Is it possible to make a top down view rotating platform? (solved)

Archive: 20 posts


Hi I am just wondering how to do this.
I am trying to create some sort off 2D hamsterball top down view and now I have a rotation circle on my track and I want that that circle pushes my hamsterball in its rotation.
Now I am wondering if this is possible?

Its the same concept as the rotating circle in this hamsterball video:

Also I am wondering how to make something on the track that speeds up the hamsterball like the speed booster they made in Rodent Derby?

I also want to say hello to this community. I am new and I discovered this website when I was searching for help. I see the place is pretty active and I am glad to be here.

You cannot rotate objects on the z-axis. You can put decorations on the drill bit from the incredibles pack or on any rotating power up such as a creatinator, paintinator, etc and it will give the visual effect of z-axis rotation but if you want to rotate a physical object then you're out of luck.2012-05-16 08:40:00

Ok and what about the second part? How do you make that?

Hold on, you don't need to rotate anything on the Z axis for what you want to do. You could quite easily create a rotating platform like the one in the video you linked. Problem is, trying to get the balls to behave correctly. Unfortunately, I'm afraid I don't know how I would go about making that work. I'll give it some thought and get back to you if I come up with something.


As for speed boosts, that's just a simple power-up set up.
Create your power-up, whatever it may be, and make sure it has a Tag on it, labelled 'SpeedPower' or something to that effect.

On the players vehicle, place an Impact Sensor, looking for that Tag. Place a Timer down, and invert it. Wire the Impact Sensor into that Timers 'Reset' input.
Place a Selector, with 2 inputs & outputs on next to it, and wire the Timer into input 2. (This is important. It must be 2.)
Then wire the Selectors output 2, into the Selectors input .

Lastly, place 2 Microchips down, and in there, place whatever your Movement setup is. So, if you're just using a Basic Mover, put that inside the new Microchip, still wired from whatever the accelerator is.
Copy that Microchip, and place it just below the first one. Open Microchip 2, and modify the Mover. This Mover is your Boost speed.
Wire Output 1 of the Selector, into Microchip 1's on/off input, and Selector output 2 into Microchip 2's on/off input.

What should happen, is when the vehicle hits the Power up, the timer empties, and the Selector changes to output 2, making the vehicle go faster.
When the timer fills up again, the vehicle returns to regular speed. This timer gives you control over exactly how long you want the boost to last.

Example photo, this is what it should look like.
Because I just made this for show, I don't actually have an accelerator, but whatever your 'Go' button is, would just be wired into both Movers.

Thank you for your help! I am going to make that and tell if it worked . Hopefully you can get up something for the rotation I would really be happy if its possible.2012-05-16 11:43:00

I'm really not sure the rotation thing will work, it'd be possible to do it kind of but it would be extremely clunky...2012-05-16 14:43:00

For the rotating platform, you could put multiple tags on it, and have a weak follower on the hampsterball (facing forward). That would encourage the hampsterball to be affected by the rotating platform. Just theorizing.2012-05-20 02:43:00

do you already have advanced movers on the hamster balls? i know a way to do it perfectly but it's quite complex, i'll try to put something together to show you when i have time, though i'm not sure how well i could explain it on here.

EDIT: threw something together that works as you described for the spinning though i'd prefer to show you in game as it's not easy to explain. what is your psn id? or you can send me a friend request if u want, even if it's just until I can show you. my psn is the same as my user name on here

Ok I will add you when I am coming online again, but with pictures you could show me what you mean .

That problem really got me stuck, so if you don't want to explain it, evret, could you just place a picture of the logic? I'm curious 2012-05-21 21:39:00

I will give you a full detail if I know how it works. Just promise me 1 day you will heart my lvl for it .

I don't know what Ev did, but if I were to solve something like this, I would put a Rotator and a Locel Space Mover on the Ball.

By using the Closeness of a Tag Sensor in the centre of the spinning disc you can determine how strong a signal you need to send to the Mover.
Being close to the centre would need a slow mover, and when further from the centre a faster Mover

Due to the rotation speed of the disc being constant (I assume?), you ball Rotator should just have the same value as the disc.
If the rotation speed of the disc isn't constant you can use a Rotation Sensor on the disc to tell how fast the Rotator on the ball should move.

i havnt been able to join him yet but i have sent him my solution, i wasnt sure if rotating the ball like that would suit his setup so i went with a different method.
also sent you something somewhere else that you might b interested in

Will it also follow the pattern then? Like that its not only rotating but also following the spinning?

You sended me something which include DLC data off the move pack and the toy story pack. Thing is I don't have those and also I don't want to make a race supported with the ps3 move.2012-05-30 12:57:00

I cannot think of a way to rotate the ball on the Z-axis (in free direction even), but if you are able to get a smooth semi-transparent ball into the game then I think it is just an insignificant detail that you can leave out; there are other ways to suggest movement, i.e. the rolling sound effect (maybe shifted in pitch as speed picks up), maybe a bit of a flicker on the ball or some sort of trail that it leaves behind.2012-05-30 14:25:00

sorry those are from the materials i used, plastic from toy story and stickerpanel from the move pack, i'll change it and send it again.
often forget about dlc coz i own all dlc so it's never an issue for me

thats not the type of rotation he is referring to, he means on a top down track, a section of the track is rotating and he want his balls to behave as if they were rolling on it, being pulled with the spin

I think I understood then. The visual rotation effect I have no idea about but creating the trajectory motion on the ball object caused by the movement of a layer behind it (thus not via physical interaction but logic) would be an interesting challenge. A moving conveyor belt would be a good start.

Thanks Evret for the solution you sended to me it really works! I just wished the joystick rotationg could be set higher then 1400 to make the rotation go faster, but really good job .

If there is anything I could do for you name it.

rotation speed isn't set by the joystick rotator, it's set by the combination of speed settings on the advanced mover on both the emitted bit of holo and the hamster ball, and the speed sensor on the emitted bit of holo2012-06-05 13:15:00
