How to make a anti-gravity sector...

[Katch]

Ok.. most of you (probably everyone) has been to ERZ1 and 2....
In the acts there are parts that you float to the ceiling without gravity boots. How do you do that on Doom Builder?

Yes, i checked the wiki...

1 - Per-Sector Gravity

Sets the gravity of the tagged sector or sectors, as a percentage of global gravity (which can be set separately using sector type 176). The floor height of the control sector is used. If it is 1000, then the target sector will have 100% gravity. If it is 500, the target sector will have 50% of the global gravity. Negative values work as well, but players can't jump down; they'll get stuck to the ceiling, unless the NOCLIMB flag is checked.

You can apply this special to the control sector of an intangible FOF to change the gravity only inside that FOF.

silly vbulletin needing ten characters

EDIT: That's a linedef, by the way.

Note: It doesn't contain info how to make it to normal again. That will be added later.

You just do it backwards I think.

Thank you, I got the gravity to move the character to the ceiling, plus I got the character to move back to the floor!

Or to make it a lot easier, and the way it works in ERZ, is to make a Per-Sector Gravity linedef type (1) to a sector with the same tag. This linedef has to have the No Climb flag on, and then you make the floor height (gravity setting) -1000, in other words, negative normal gravity. This'll flip the character and pull him to the ceiling with normal gravity. No custom power needed. This can also work with linedef types 223.

But if you use that, you'll fall down again the moment you exit the sector, which means you can't exit the sector quick enough, and the Gravity Boots icon won't display (minor detail).*

It requires less work if you use custom power control sectors, except for the normal gravity flip, but that is pretty easy too.

*Or you'll have to tag every sector for it to work, and that does not only take alot of work, it also gets in the way if you want to edit some flats and textures in 3D mode.
