It's designed more for 2.5D so it has the 3D option but the code is specifically made for 2D. An option would be tearing it apart but that would take much time.

Graham, would your kit work in 3d?

This seems to be much more frustrating then I thought  :-\

sebaslive, I added a RigidBody to the platform and this helped a little in the fact that its stays on the platform BUT slides slightly for the first second but then moves with the platform.

Do you think the Velocity has something to do with it?

Thanks

Nick

From the tests I did, if you add a lot of mass to the player, around 1000 it wont move, but you would need to add a ton more force for it to jump and such.

It also appears to move a lot less based on how fast the platform is moving since it doesnt give it enough time to slide off.

Also, a ton of drag would have the same effect as the mass but again would require a ton more force.

I dont find these to be the best solutions but they work...ish

Yes sebaslive, my kit is in fact a 3d solution, just running on 2 axis'. If I knew why it works for me I would share, but I can't see what exactly I am doing differently.

I can tell you my character has a mass of 1.8, so I don't think upping the mass is a solution I would go with since it adds other issues.

Also, I can make my platforms go extremely fast and the character doesn't move an inch. Also my platforms do not have a rigidbody.

The only other thing I can point out is, my platforms move using the "iTween Move To" action. You say you move yours with velocity?

Graham have you tried this without your kit?

I'm using the 'itween move to' as well.

Creating a new scene with no custom scripts or addons included and my platform still behaves the same. If you don't mind could you create a test scene so I could compare settings to yours?

Seems like the only way to see whats happening with our setup.

Thanks

Nick

Hi Sebaslive,

Not heard back from Graham but i have been testing and thought i would try and move the platform without using iTween.

I used Translate and did a ping pong motion using C# and did the same process again and found that the player sticks to the platform now. I had to make the moving platform kinematic and have the platform move using FixedUpdate.

Maybe there is something wrong with iTween?

Sorry coxy, I haven't had a chance to try it out yet. I do use iTween on mine, it doesn't cause any issues here.

You mention having to set the platform as kinematic. My platforms do not use a rigidbody component! Maybe that is your issue.

Hi graham. I've tried it without a RigidBody but it behaves the same with iTween. That's why I was after a test scene to compare. No worries if you haven't got time..

No I haven't, a lot of overtime lately. If you wanna send me your scene though I can take a look. It's quicker than making one from scratch myself.

Hey Nick,

I played with your scene for a little while, unfortunately I don't know what's wrong with it and I'm not able to go much deeper into it right now.

Sorry,
Graham

OK thanks anyway Graham

Would be interesting to know what's different in your games setup.

But i think iTween has got a problem with using FixedUpdate (realtime) feature?

Not sure if you noticed, but the entire project is available on the Unity Asset Store.

You can always dissect it to see what you are able to find out.

Hi, ive finally got around to looking over your project and i cant see what the difference is? strange. Would be great if someone had a sample scene with it working.
