How do I make a float platform

Hi Guys, I am new to Construct 2 and am trying to make an action game, where a fish swims at the surface of the ocean and you can tab the screen to make it jump or dive.

What i have tried is make the fish a platform and make gravity 0 so that it doesnt fall, and make float at the certain height. but now without a solid, the fish cannot jump (not even mention dive).

Could some one point me to the right direction? Is a platform behavior the right one to use?

Thanks heaps

any one?

try the physics behavior instead. With that you can apply a impulse in a direction (for your jump) and you could do the same with reversed gravity for your dive.

interesting.... i might try this:

initially, gravity = 0 to make it float,

on jump, impulse up and apply gravity.

on dive, reverse gravity and impulse down

Thanks
