The Engineer

The PDAs are default weapons for the Engineer, consisting of the Construction PDA and Destruction PDA, which the Engineer uses to respectively construct or destroy his various buildings. The Construction PDA is a calculator-style device, whereas the Destruction PDA looks similar to a stereotypical hand-held detonation device.

These gadgets are not regular weapons, as they cannot be used to attack; they mainly serve as a visual cue to the player and others. While the player is using either PDA, a unique menu appears on-screen to allow the player to build or destroy available buildings.

Upon selecting one of the PDAs, a superimposed HUD appears in the middle of the player's view. Though it lists all four available buildings, only the highlighted choices will be selectable. Selection of the buildings is done through the preset numbered keys.

The selection keys will only function on the appropriate PDA under the right conditions. Should the player have insufficient Metal, they will be denied access to certain buildings on the Construction PDA. Gathering Metal will re-enable the choices once the player has a sufficient amount. Conversely, the Destruction PDA will only destroy builds that have already been constructed. The Destruction PDA cannot be used to destroy buildings currently being sapped by the Sapper.

If a player chooses to construct an available building from the Construction PDA, the player model will then appear to hold a Toolbox, and the player will see a template on the ground in front of them. This template shows the orientation of the chosen building. While the template is visible, secondary fire adjusts the building's orientation by 90 degrees counter-clockwise, and primary fire starts the build process.

Pressing the last weapon used key or primary fire key will cancel either PDA menu, and return the player to their previous weapon.


Demonstration

Console Information

Note: The console versions do not have a separate Destruction PDA. Both are instead are handled by the Construction PDA, which serves as a single PDA for both functions. After choosing the proper weapon slot to activate the PDA, the player uses the right trigger or 'R2' to construct the selected building if enough Metal is available, and the left trigger or 'L2' to demolish the selected building if it has already been built.

Unused content

  • The item schema contains a list of ranks related to 'Health Dispensed', intended to be used by the PDA's strange variant. However, it instead simply ranks up based on Sentry kills and uses generic names and values.

Bugs

  • The unique and strange variants Construction PDA viewmodel are not affected by the "Use minimized viewmodels" option.
  • If a Strange Construction PDA is equipped in Mann vs. Machine, the Engineer can lose upgrades and the money spent on them if they are using the Upgrade Station at the same time as another player using the Engineer's Dispenser or Teleporter.
  • If a Construction PDA is in use when hit by a object or projectile, the options to build will disappear.
  • The Destruction PDA does not always play the draw animation.

Trivia

  • There is a PDA1 Token in items_game.txt, but it is unused. Internally, the Engineer's Construction PDA and the Spy's Disguise Kit fall under this slot.
    • The PDA2 token is used for crafting the Spy's unlockable watches, which fall into the PDA2 slot, and can be made by crafting together 3 Spy watches. This is the only use for the token.
    • Crafting 3 Unique Construction PDAs together or Rebuilding a slot token with one will not create a PDA1 token.
  • The tf_build_menu_controller_mode console variable can make the PDA act as both a build and demolish tool, like on consoles.
  • The pda_click console command displays the Engineer pressing a button on the PDA, only visible to other players. Using this command does not construct a building, and is just for miscellaneous reasons. Also, the animation does not perform if the player is crouching.
  • The Construction PDA is based off the Texas Instrument's TI-2500 Series Datamath Calculators, which first appeared in 1971.

Notes

  • Switching between PDAs and the last weapon active will not result in the usual delay caused by weapon switching.
  • The Pip-Boy cosmetic changes the look of the Construction and Destruction PDAs' superimposed HUD.
