Common Tricks

See also: CommonTricks

Screen abuse

Wrap abuse

In many games, the positions of the character, enemies and/or objects are stored in a way coresponding to the screen's coordinates. Mostly in 8-bit games, each of the horizontal and vertical positions is stored in only one byte. You can sometimes overflow or underflow the values so that you can make the character, enemy and/or object disappear on one edge of the screen and reappear on the opposite edge.
Note: This trick can sometimes be abused even if a game stores the positions in more bytes, but it will take longer after the character, enemy and/or object disappears and before it reappears.

Scroll abuse

In some non-auto-scroller games, you can sometimes abuse the scroll itself to achieve some advantages:
Note: This abuse is often involved in screen wraps.

Note: By "jumping" the author means "ascending" that cannot be interpreted as "falling".
The most important thing to concern inside a wall is when and how the wall will eject you. Below are (some of) the rules of ejection:
  1. As long as the wall is ejecting you either horizontally or vertically, your corresponding momentum will keep being reset.
  2. The wall will certainly eject you upwards onto its top as soon as:
    • The bottom of your feet are higher than the centre of the topmost block of the wall, which you have been sunk into.
    • Your vertical momentum has become about zero.
  3. The wall will ignore ejecting you horizontally, until:
    • One frame has elapsed since you entered it.
    • The bottom of your feet are lower than the centre of the topmost block of it, which you have been sunk into.
  4. As long as you are falling inside the wall, you will be ejected against the direction of your last horizontal acceleration, except for LEFT+RIGHT.
    • Pressing LEFT+RIGHT reverts the direction of ejection every frame as long as you are falling.
  5. As long as you are either on any "ground surface inside the wall", or you are jumping inside the wall, whether and how you will be ejected is determined by your key presses.
    • If you are not pressing towards the direction of ejection or LEFT+RIGHT, you will be ejected. The direction of "non-falling" ejection is simply determined by whether there are solid blocks on your sides:
      • If there are solid blocks only on your right side and none on your left side, you will be ejected to the left.
      • If there are any solid blocks on your left side, you will be ejected to the right.
    • If you are pressing towards the direction of "non-falling" ejection or LEFT+RIGHT, you will move as if you were not inside the wall.
Note: Whether a block is on your left or right side is determined with whether you are more close to its left or right edge than to the opposite edge.
TODO: verify all these above.

Footnotes

[1] This section is still under construction and its contents may be incomplete.
[4] These movies don't have links to them simply because I've never submitted them anywhere. Still, it may be possible to find some of them "spoiled". I may submit them somewhere sometime.
[6] These games only receives input every other frame, which could be annoying.
[9] Gwahahahah! I discovered lots them myself! Well, seriously and fairly speaking, credits should be given to many people including but not restricted to 黑暗人(Dark Man), 暗黑妖怪(Dark Monster), Kaz, ljffdb2, zggzdydp, @joachim(aka. Princess Joker), rfv, and of course myself.

Comicalflop: I don't get the point of this page. All info can be found elsewhere, and there's no need to have it all here. Also, technical descriptions such as "This game is heavily glitched" are uninformative and stupid; most of the runs on the site use glitches of some sort too.
moozooh: Comicalflop, this is a page created by klmz in his subdomain. What's your problem?
pirate_sephirothHey, why there's nothing about Megaman Zero? check the gruefood and you find that awesome run by Gigafrost...
klmz: Oops edit conflicts! It seems that pirate_sephiroth undid my v11...
