ive been tryna make this xmas themed level in srb2 and i wanted to add a secret in which you have to spindash to break the wall.... question is how do i properly do it?? ive made it a sector tag with its property connected to an external linedef but all im getting is the wall collapsing sound and not the wall itself collapsing

Linedef type 255 - SRB2 Wiki

Most Linedef Type pages on the Wiki have an example wad file you can view to check how to use the linedef. Hopefully looking at this will help you figure out what you did wrong.
