Common Characteristics / Patterns In Tech Charting
Common traits of Tech charting, and how to create them
• Pseudos
Pseudos are basically double-hit patterns. They work similarly to the multi-hit tiles in World RJ, where you need to press two keys at once. These are the most common pattern in the entirety of Tech charts, as they elevate the difficulty of a level by a high amount. These are specifically hard-coded to work when multiple keys (in this case, two) are pressed at the same time, as declared by some developers.
The pseudos in the picture above are made using 30° angles, which is the most common angle for pseudos at fast songs (300 BPM or above), but another angle that tends to be used frequently is 15°, for slower parts of songs (150 - 300 BPM) or for tighter hit windows. If a song is slower than 150 BPM, you can use smaller angle turns for pseudos using the insert custom angle option.
Interestingly, when twirls are used in the second tile of a pseudo, you can add tiles at a 60° angle in relation to the second tile of the pseudo and it will work. This happens because the angle distance between the planet on the previous tile and the next tile stays the same in this type of twirl, which involves On-Beat Rotation.
This is also valid for 15° pseudos, where instead of the next tiles being at 60° for it to work, they are at 30°.
Pseudos can be mixed with other shapes for more interesting gameplay. They can give some good variety to the level, and make it more dynamic, as well as, of course, making it harder as well.
You can also use more twirls on pseudos to create double-speed pseudos (not final name). These act like normal pseudos, but, as the name suggests, they need to be hit at double the current BPM of the level.
Pseudos, while they can just stay On-beat, they also can skip a beat if you use 330° for 30° pseudos, or 345° for 15° pseudos, similar to a 360° turn.
The rule for the twirl on the second tile of the pseudo is also true here, while having an On-beat Rotation that adds up to 360°.
Mid-spins can also be used to create pseudos, and they have interesting interactions relating to On-beat Rotation.
Another commonly used type of pseudo are the triple pseudos, which requires 3 keys to be hit. These are normally used at the 4th beat of a 4/4 song, but there's no general rule on where you should use these. Quadruple pseudos can also be used, which require 4 keys at once to hit, but are not as common as the ones listed before, and are not hard-coded to be hit correctly when pressing all the keys at the same time, unlike the previous patterns.
• Zips
Although not exactly a common trait only in Tech charting, zips are fairly more used here than in classic charting. Zips consist of a really basic pattern, where you use the same angle repeatedly for the next tile, using twirls on all of them. The most common types are from the base angles provided by the editor itself (I.e. the tile key shortcuts).
These, most of the time, are already enough for a regular Tech chart. Note that you can extend these for as much as you want.
