Killing Boss opens door Advice. 4.5.9

[TheRetroBro]

Im using LR platformer mod.

For my next Game I want to learn how to open a section of the screen after the boss death:

GOALS:
Warp into Boss room
Kill Boss
Door appears (or wall to right left top bottom opens etc opens) so you can progress.

Not sure how to attack this. I'm semi familiar with the concept of screenbytes and screenflags.

Thank you!

Hi RetroBro,

There are a few ways to accomplish that. One way is to create a door tile type, make it act as a solid, and then change all those tile types on screen to zero if the boss is killed. Here's a forum post about how to change all tiles of a certain type at once: http://www.nesmakers.com/index.php?...-to-bring-back-changealltiles.6727/post-35348

An easier way that takes way less code modifications, would be to warp to an identical room with the door removed when the boss is killed.
