Chrono Trigger internals - Z-Plane
« on: May 13, 2012, 02:16:51 pm »
Hello!

I'm studying how does Chrono Trigger uses Z-Planes to create many perceived "levels" on a single map.
I understand trivial cases like how do the two planes interact, transitional neutral, solid and walkable tiles but as far as I can see there are additional properties on each map tile. I'm wondering if someone knows what does the Solidity Mod integer and ZPlane Solidity flag do?

Thank you in advance!

It just uses the 2 x 16 colors and 1x 4 colors layers that are available in the video mode.
A few smaller sequences like the jet bike race  and a ending use mode 7 pseudo 3D

Hmm... So those two properties are used only with Mode-7 3D mode?
I thought they were used in conjunction with the Z Plane property - for example in Zeal Castle map Plane 1 tiles have Solidity Mod = 1, Plane 2 Solidity Mod = 2 and Transitional Walkable tiles have Solidity Mod = 3. But that may be a coincidence or it may not be used here at all.

Thanks for the information!
