• Discussion thread
• Game speed is not emulated properly in JPC-RR at current. All speeds are speed 8.
• Stunner or Shield items and other random drops are not used (or using them counts as a different category).
  • Nach: Really? Who decided this?
    • Svimmer: Slamo tried manipulating the drops, but didn't find a real way (it's on the second page of the thread). The logic behind not using them at all is a) it's too haphazard if they can't be properly manipulated, b) it would give the run a cheeky feel, like in some levels you're "supposed" to have no fuel. also, if this run abstains from using them altogether, that would leave more space for another run later (if it was found out how to manipulate them) that does use drops as much as possible. I don't know how Slamo feels about this currently. I'm not stating this as an undisputable truth.

Naming Conventions & Abbreviations (as per Svimmer who forgot his nick, not final version)

• Guy/The Guy - the character you're controlling
• Enemies (see Enemies section)
• RTP/BTP/TTP - red/blue/teal teleporter
• teleporting
• phasing - phasing out blocks
• phase in/phase out - what blocks do when phased
• thrusting - moving around using the jet pack
• running - looks to me like it's more a run than a walk
• trapping - monsters get trapped inside phasing-in blocks
• tank/dtank - fuel tank or double fuel tank
• block - sometimes called "tiles", but this seems more common
• phasable blocks: pink, lred, dred, crate
• ladder/uladder/dladder/aladder - that is "up ladder" and "down ladder" or more generally "autoladder"
• gem - what you collect, manual has "emerald gem"
• charger/drain - the ones that replenish/drain fuel
• spear - the hidden trap that shoots up from the ground
• RFF/BFF/TFF - red/blue/teal force field: manual calls them "barriers"
• RS/BS/TS - red/blue/teal switch: manual calls them "buttons"
• moss/ice - manual "sludgy bricks"/"icy bricks"

• ladders should be just "l/ul/dl/al" because they're so common? in manual we have "moving ladders"
  • your opinion here

• should the manual's "moving platforms" be called "conveyor belts"? because if it's abbreviated MP it's hard to guess/remember it's a "moving platform". So I suggest "LCB/RCB" for left-right conveyor belt. Otherwise maybe "lbelt/rbelt" or "lcon/rcon"?

• spikes - the manual has "stationary spikes" for the trap and "spikes (spinning)" for the enemy type: I suggest we call the first type "spikes" and the second "spinner"

• The Guy? Or should we just say "You", as in "You are invulnerable after picking up the shield"?

Open Questions

• Did someone measure how long it takes (in frames and in pixels) to accelerate to the terminal speeds running/thrusting?

• Also missing ladder climbing/autoladder speeds and moss/ice, but those can be added in when they've been encountered in-game. Also speed when rapidly climbing a ladder by jumping.

• Also someone mentioned you walk faster when out of fuel? At what speed then?
  • Nach: I don't know about walking, but jumping is certainly faster without fuel.

• Can someone confirm my vague memory about that trapped enemies can't hurt you even if they jut out? If so add to tricks, please!

• Can enemy movement patterns be manipulated other than by one's own positioning, i.e. through the RNG? How do trackbots "track" you exactly, which rules do they follow?

• Can the teleporting to a different colour TP trick occur on any of the official levels (are there ever that many teleporters)?

Randomness

Enemies

Known tricks

Movement

• You can jump off an empty block if you started above it.
• You can hold down while flying to keep your height, or phase horizontally.
• Phasing up/down shifts your position to directly adjacent to the block.
• Phasing up/down stops your movement.

Enemies

• Enemies always teleport when hitting a TP.
• Sometimes certain enemies move faster than others of their kind.
  • Applies at least to: Marbles, Springs?
    • Nach: Some Marbles change speed over time, not entire sure why.
  • May have something to do with their spawn square. (unconfirmed)

• Missile does a 90 degree clockwise turn when it hits a wall, there is no randomness.

Miscellaneous

• After dying you can still finish the level by landing at/lifting to the door.
• You are invulnerable during teleportation.
• Teleporters may teleport to the wrong color if the level has too many of them.

ToDo

• Adding the remaining levels and their images (http://tas''''videos.org/images/gameresources/jetpack/level_XX.png) replace XX with level number.
  • Describe what is important in each level
  • Different route strategies.
• Adding each enemy type in as a separate picture with more detailed information attached
