Floating Platforms

[gregacuna]

Hey All...

I'm creating 3d system of floating platforms in the sky. I want them to gently move and figure I can do a simple iTween, but also thought to have them react to player's weight very subtly.

How would I use Playmaker to have an object appear to be floating in the air and respond to the weight of a player?

Hi,
Maybe you could make a empty parent and place you platform in it,
Then tween the movement.

On the platform have a trigger and when the player 'lands' on the platform, animate the vertical movement with the animator

If you would use weights on the platforms it will get very complicated.

Thanks Djaydino...that's pretty close to what I was planning, but was wondering if using physics would be too complicated and/or heavy. I'll try your suggestion and see how it looks. Cheers!

Hi,
You could have multiple animations and for example get the y velocity (drop speed)
and have less or greater vertical movement on your platform depending on that drop speed.

But it can be done in physics

I tried something like this :
Have the platform still as a child and disable gravity.
You need to freeze rotation on your platform (or clamp if you want to have some rotation).
Have a 'Get position' action (get the y position)
Then have a float compare and set a position below the platform (-3 for example)
if it reaches below -3 then use an 'add force' to 'push' it back up then get again the y position and compare
If it reaches 0, set velocity to 0 (to make a more smooth stop, you might need to use a float interpolate)
and set your platform 'Is Kinematic' else it will go down again.

I added a scene i made to show you how.

Hey Djaydino...

That's super nice of you. I don't have time to test it today, but as soon as I do I'll send you a message. Thanks so much! Have a great day!

Hi,
No problem
