Platform linedef types
A platform is basically a floor action involving two heights. The simple raise platform actions, for example, differ from the corresponding floor actions in that if they encounter an obstacle, they reverse direction and return to their former height.
The most often used kind of platform is a lift which travels from its current height to the target height, then waits a specified time and returns to it former height.

Platform Targets[edit]
- Lowest Neighbor Floor
This means that the platforms "low" height is the height of the lowest surrounding floor, including the platform itself. The "high" height is the original height of the floor.
- Next Lowest Neighbor Floor
This means that the platforms "low" height is the height of the highest surrounding floor lower than the floor itself. If no lower floor exists, no motion occurs as the "low" and "high" heights are then both equal to the floors current height.
- Lowest Neighbor Ceiling
This means that the platforms "low" height is the height of the lowest surrounding ceiling unless this is higher than the floor itself. If no adjacent ceiling exists, or is higher than the floor no motion occurs as the "low" and "high" heights are then both equal to the floors current height.
- Lowest and Highest Floor
This target sets the "low" height to the lowest neighboring floor, including the floor itself, and the "high" height to the highest neighboring floor, including the floor itself. When this target is used the floor moves perpetually between the two heights. Once triggered this type of linedef runs permanently, even if the motion is temporarily suspended with a Stop type. No other floor action can be commanded on the sector after this type is begun.
- Ceiling
This target sets the "high" height to the ceiling of the sector and the "low" height to the floor height of the sector and is only used in the instant toggle type that switches the floor between the ceiling and its original height on each activation. This is also the ONLY instant platform type.
- Raise Next Floor
This means that the "high" height is the lowest surrounding floor higher than the platform. If no higher adjacent floor exists no motion will occur.
- Raise 24 Units
The "low" height is the original floor height, the "high" height is 24 more.
- Raise 32 Units
The "low" height is the original floor height, the "high" height is 32 more.
Varieties of Platforms[edit]
A platform can be activated by pushing on a linedef bounding it (generalized types only), or by pushing on a switch with the same tag as the platform sector, or by walking over a linedef with the same tag as the platform, or by shooting a linedef with the same tag as the platform with an impact weapon.
A platform can move with speeds of Slow, Normal, Fast, or Turbo. Only the instant toggle platform moves instantly, all others move at the platform's speed.
A platform can have a delay, in between when it reaches "high" height and returns to "low" height, or at both ends of the motion in the case of perpetual lifts.
A platform action can be a texture change type, in which case after the action the floor texture of the affected floor, and possibly the sector type of the affected floor are changed to those of a model sector. The sector type may be zeroed instead of copied from the model, or not changed at all. These change types are referred to below as Tx (texture only), Tx0 (type zeroed), and TxTy (texture and type changed). The model sector for the change is always the sector on the first sidedef of the trigger (trigger model). If a change occurs, floor texture is always affected, lighting is never affected, even that corresponding to the sector's type, nor is any other sector property other than the sector's type.
