4.5.9 metroidvania SWIMMING! almost complete

[CalFlyheight]

ok so,
i have an unlockable swimming variable in my game and its nearly finished but iv got 1 strange problem with the gravity....
i have a tile that changes my action step to swimming and then my physics sorts it out and goes to swim gravity BUT when i jump in and cross my swim tile for the first time it looks like gravity is sped up to the max and i fall super fast to the ground. then the swim mech works perfectly after iv touched a solid tile. if i just drop in on the ledge and then move ahead the gravity is perfect. its driving me crazy!
at this point i want to see if anyone has encountered anything similar?

you should try to alter the gravity engine when needed (when a variable is set "on"... maybe when your player is in those water tiles, for example)
Check that topic:

Have different gravity on specific screen types (4.5.9)

Here's a tutorial for making levels with different gravity on specific screens based on screenType. This can for example be used to make underwater levels or space type levels. PS! This tutorial is made for platform type games. 1. Make a backup of doHandlePhysics_PlatformBase.asm It's...

thanks @dale_coop i did use that one to get to where i am. what im looking through now is the dohandlephysics script to see why my adaptation is ignored on collison with the tile. but its very unusual that i can tap A and then it will do the correct physics, or if i touch a solid tile it will go to correct physics...
both my tile script and physics are both very simple and lined up.
