Wow - finally. The candle item works and is finished.

Thanks minmay!

I have a few new questions: what does the reflection tile drawing mode do? And also what is the point of an occluder and what is it used for?

> what does the reflection tile drawing mode do?

Skuggasveinn has explained it in LoG2 editor tutorial - part 4 - Creating water inside your dungeon @ 4:25

If you haven't already done so, I suggest downloading all of his LoG2 tutorials with https://youtube-dl.org/

And also what is the point of an occluder and what is it used for?

Add a wall to your level (like a ruins wall, preferably outdoors with lots of stuff around) and disable the model to see for yourself what it does

It occludes.

So what is the point of it? is it for performance so it doesn't load the models the player usually wouldn't see or something?

[7Soul]

Exactly, every game does it

They are super important, some engine create their own mesh from models to use for vision culling, the Grimrock 2 engine uses models that you have to define as an Occluder model for that specific task.

Perhaps long overdue but I decided to record a short video about occluders and there function and how you can see what they are about. Hope it helps.

Two more questions: first, if the player creates a party, changes the position of champion 1 and champion 2, then imports that party
into a different mod, would the game remember the original Ordinal or make a new one based on the party's formation when it was imported? Second, is there some sort of offset function that can be used repeatedly on the same object? Such as using something like setSubtileOffset but if you call it twice on the same object it would move it twice? Something like this?

Code: Select all

teleporter_1:setSubtileOffset(2, 2)

but if I call it again, it would move it again? (or alternatively, could I do something like

Code: Select all

local offset = teleporter_1:getSubtileOffset()
teleporter_1:setSubtileOffset(offset + 1)

GameObject:getSubtileOffset() returns two values:
- x subtile offset
- y subtile offset
( see https://www.lua.org/pil/5.1.html )

If you want to change the subtile offset by some amount, you could do it like this:

Code: Select all

local x, y = teleporter_1:getSubtileOffset()
teleporter_1:setSubtileOffset(x + 0.1, y + 0.1)
