| speed | How quickly the ceiling moves |
Lowers a ceiling to the height of the highest floor sorrounding it. If tag is 0, then the sector on the line's back side is used.

| speed | How quickly the ceiling moves |
| height | Absolute height of the move |
| neg | Whether or not the destination height is negative |
Moves the ceiling of affected sectors to an absolute height of (height * 8) units. If the destination height is negative, then neg should be 1, otherwise it should be 0 for a positive height. If tag is 0, then the sector on the line's back side is used.

| speed | How quickly the ceiling moves |
| crush | Amount of damage to apply |
Lowers and raises the ceiling of the affected sectors continually, applying crushing damage to anything underneath it. The ceiling will rise at half the speed at which it lowers. If tag is 0, then the sector on the line's back side is used.

| crush | Amount of damage to apply |
Lowers the ceiling of the affected and applies crushing damage to anything underneath it, then raises the ceiling back up to its original height. The ceiling will rise at half the speed at which it lowers. If tag is 0, then the sector on the line's back side is used.

| target | How to determine the ceiling's destination height |
| flags | Flags for the move |
This special encapsulates BOOM's generalized ceilings. Flags are:
| Value | Meaning |
|---|---|
| 0 (0x00) | No change |
| 1 (0x01) | Zero sector's special |
| 2 (0x02) | Change sector's ceiling picture |
| 3 (0x03) | Change sector's special |
| 4 (0x04) | Use numeric model if set, trigger model if not |
| 8 (0x08) | Raise ceiling if set, lower it if not |
| 16 (0x10) | Cause crushing damage if set |
Target can be one of the following:
| Value | Target |
|---|---|
| 0 | Height units above/below current height |
| 1 | Highest surrounding ceiling |
| 2 | Lowest surrounding ceiling |
| 3 | Nearest surrounding ceiling |
| 4 | Highest surrounding floor |
| 5 | This sector's floor |
| 6 | Height units determined by shortest upper texture on sector |
If tag is 0, then the sector on the line's back side is used.
| tag | Tag of affected sector |

| dspeed | How quickly the ceiling lowers |
| uspeed | How quickly the ceiling raises |
| silent | Set this to 1 to prevent the crusher from making noise |
| crush | Amount of damage to apply |
This special encapsulates BOOM's generalized crushers. It is the same as Ceiling_CrushAndRaiseA except that it takes an argument to control the "noisiness" of the crusher.
