Miniturbo

2023-08-30T15:18:47Z

Vabold: /* Relevant code */ Style fix

The '''miniturbo''', or '''mini-turbo''' is a speed boost technique present in every Mario Kart game.

== Overview ==
When performing a drift, assuming you are using manual transmission, a miniturbo will charge up after a certain period of time, and when you release the drift, you will get a boost from this miniturbo. Miniturbos charge at different rates depending on the joystick direction held during the drift. Although the GCN joystick has an input range from 0 to 255 on both axes, all inputs are simplified and reduced down to an input range from 0 to 14 on both axes. These are also referred to as -7 to +7 to ease understanding even more. Miniturbo charge is a numerical value that counts upwards from 0. If you are performing a right drift, any input from -7 to +2 will increase that value an increment of 2 every frame, and any input from +3 to +7 will increase that value an increment of 5 every frame. Conversely, if you are performing a left drift, any input from +7 to -2 will increase that value an increment of 2 every frame, and any input from -3 to -7 will increase that value an increment of 5 every frame.

== Types ==
There are three types of miniturbos in [[Mario Kart Wii]]:

''TO DO: Boost lengths and corresponding images for each type.''

=== Standard Miniturbo ===
This is the most common type of miniturbo. It is charged when miniturbo charge counter becomes greater than 270, and is possible on both bikes and karts. Upon reaching at least 150 charge, individual blue sparks begin appearing at the back of the vehicle the next frame.

=== Super Miniturbo ===
This miniturbo is only possible on karts. Beginning on the same frame that the standard miniturbo is fully charged, a new super miniturbo counter begins counting from 0 up to 300. It is charged when the super miniturbo counter becomes greater than 300, and individual orange sparks appear the frame after the charge counter reaches at least 180. The player may be tempted to release the miniturbo after a standard miniturbo is charged, but should they continue to hold the drift for slightly longer until the orange sparks will appear, they can instead release a super miniturbo.

=== Standstill Miniturbo ===
This miniturbo can be begin to be charged by holding accelerate and brake (A and B) simultaneously when[[Internal velocity | IV]] is between -10 and 10. This increments a standstill miniturbo charge counter by 1 per frame until it becomes greater than 75, after which the standstill miniturbo can be released.

Offroad glitch

2023-08-09T18:59:53Z

Vabold: Use Tabber for Gecko codes

The '''Offroad Glitch''' is a bug with specific jump pads which negates the following speed modifiers.
* Wheelie bonus
* Mini-turbo/trick/zipper boost
* KCL flags
* Shock speed
* Crush speed

== Technical description ==
To perform the glitch, land from a variant 3 jump pad without touching a variant 4 jump pad. [[Mushroom Gorge]] is the only Nintendo track where this is possible, and can be easily activated by using the [[Mushroom]] item on the first ramp to skip the red mushroom, or by driving backwards and backing up into the ramp.

When in this state, offroad becomes indistinguishable from slippery road. Even though KCL speed is negated, KCL rotation is still accounted for, and the rotation for offroad matches the rotation for slippery road in all cases.

Mushroom Gorge uses two exclusive jump pad variants: 3 and 4. Variant 3 is assigned to the ramps, and variant 4 is assigned to the mushrooms. These variants are unique because they unconditionally negate the above speed modifiers, and their intended behavior is to restore them when touching the ground. However, the game developers mistakenly believed that variant 4 would always be activated before landing.

== Relevant code ==
The following code is written in C++, and has been edited to only include relevant parts. Irrelevant code will be marked with <code>// ...</code>.<syntaxhighlight lang="cpp" line="1">
// This is run when the game recognizes we're interacting with a jump pad
void Kart::KartMove::tryStartJumpPad(int variant) {
// After various checks, generically set the flag for jump pads
KartState *state = mAccessor->getState();
state->bitfield0 |= FLAG_JUMP_PAD;
// ...
if (variant >= 3 && variant <= 4) {
// ...
// Set the flag for negating the speed factors
state->mFlags |= JUMP_PAD_FIXED_SPEED;
}
if (variant == 4) {
// Set the flag for mushroom-specific jump pads
state->mFlags |= JUMP_PAD_MUSHROOM_TRIGGER;
// ...
}
// ...
}
</syntaxhighlight><syntaxhighlight lang="c++" line="1">
// This is run once every frame generically
void Kart::KartMove::tryEndJumpPad() {
KartState *state = mAccessor->getState();
// Check to see if the flag for mushroom-specific jump pads is set
if (state->mFlags & JUMP_PAD_MUSHROOM_TRIGGER) {
// If so, check to see if we just landed on the ground
if (state->mFlags & GROUND_START) {
// Unset the mushroom-specific jump pad flag
state->mFlags &= ~JUMP_PAD_MUSHROOM_TRIGGER;
// The game falsely assumes that JUMP_PAD_FIXED_SPEED can only be set if the mushroom trigger is set
// As we see above, this is not always the case, leading to the offroad glitch
// Unset the fixed speed flag here and only here
state->mFlags &= ~JUMP_PAD_FIXED_SPEED;
// ...
}
// ...
}

// Check to see if we just landed on the ground and that the mushroom-specific jump pad flag is not set

== Article improvements ==

We should implement Tabber (or a similar extension) for Gecko codes. Displaying all regions at once doesn't look great and makes it harder to navigate.

I'm also not the best writer, I'm much more of an editor.
