Very challenging but I learned new things
The collision was not that hard, you take your visual geometry and optimize it so only the bumps and whatever remain
Then, you simply extrude all the edges where you want walls to be
I didn't really change the code
except so the game doesn't load the map but rather the level instead
Scripting don't ask

there are like 1600 event sequences
so that means that modding posibilites are far away from reality
you need to know additional knowledge to be able to produce something advanced
No you could easily make everything in the new versions of the editor
ye but like as you said you had to do scripting
i hope you didnt mean opening visual studio
no, you open the events window in the editor
i thought it needed additional coding knowledge
scripting is like "lock object", "spawn enemies" type of stuff
