Tinkerer, I'm afraid the engine is quite limiting in this kind of gameplay. I'm not super competent in this question but these are the facts I know.
- There are no jumps in game mechanic.
- Movement of characters is affected by AI grid, which is rarely updated dynamically (it is though because you can move and destroy items).
- Whyle moving item to trigger is possible, characters can walk only on top of few items, which has specific physics and setup (WalkOn flag).
- You will not be able to make a moving platform with characters on top of them.
You though can try to put on/off stage items alike to 1m_Cellar_A_Platform_A_Item template inside the puddles of lava to emulate something similar to what you described. But I can't gurantee that AI grid will adjsut to the changes. Indeed better solution will be to create a predefined set of global items and switch thier positon and appearence on stage in osiris with timers or other logic.
Happy modding!
