Launch Pad

Before this: Reacting to the Game, Vectors and Colors

Run onto the pad and it throws you into the air, and forward in the direction you are looking.

How it works

You need

a brick with an Attached Zone just above the pad

zone "Zone Ref" -> chip pad

Code

// Upward push.
const UP = 1500.0
// Push in the direction the player looks.
const AHEAD = 1000.0

@left in pad: zone

on ZoneEntered(zone = pad) -> (character) {
  let look = character.GetAim().Direction
  let flat = Vec(look.x, look.y, 0.0)
  character.AddVelocity(linear = flat * AHEAD + Vec(0.0, 0.0, UP))
}

Wire it

Compile the chip and paste it in-game.
Wire the Attached Zone’s Zone Ref to pad.

Check it in game

Walk onto the pad looking straight ahead: you fly up and forward.
Walk on looking to one side: you fly toward where you look, not where you walked.
Walk on looking straight up or down: you go almost straight up.
Stand still on the pad: nothing more happens until you step off and back on.

Change it

Change UP and AHEAD for a bigger or smaller jump. Start small: the numbers are speeds, and a large one sends a player very far.
Always launch the same way, whatever the player looks at: replace the whole push with a fixed vector, such as Vec(800.0, 0.0, 1500.0).
Turn the pad off with a switch: add @left in armed: bool, wired from a Switch’s Enabled, and wrap the push in if armed { ... }.

The zone event gives the player who stepped on (Reacting to the Game). GetAim() reads where they look as a direction vector. Its height is set to 0, so the forward push stays level. It is weaker the more steeply the player looks up or down. The upward push is added on top (Vectors and Colors). * AHEAD scales all three parts of the vector at once. AddVelocity adds to the player’s speed rather than replacing it, so a running start carries into the jump.
