Some features may change during development of Ikemen GO, making content created for older versions of the engine sometimes become incompatible with newer versions. This page explains how to update the deprecated code.

Character Changes

State Controllers

HitScaleSet

This state controller was dropped altogether in Ikemen GO 1.0. Numerous other methods are available to build your own scaling systems.

Triggers

AnimElemLength

As a property of the current animation frame, AnimElemLength is now included in the AnimElemVar trigger, as AnimElemVar(time).

BgmLength

As a property of the current bgm, BgmLength is now included in the BgmVar trigger, as BgmVar(length).

BgmPosition

As a property of the current bgm, BgmPosition is now included in the BgmVar trigger, as BgmVar(position).

FramesPerCount

As a fight screen parameter, FramesPerCount is now included in the FightScreenVar trigger, as FightScreenVar(time.framespercount).

GetHitVar(attr)

The attribute parameter is now of type string instead of int, aligning it with the HitDef attr assignment as well as the HitDefAttr trigger.

;trigger1 = GetHitVar(attr) = const(AttrAerialSpecialProjectile); old syntax
trigger1 = GetHitVar(attr) = A, SP; new syntax

GetPlayerID

GetPlayerID was removed in Ikemen GO 1.0. It can be replaced with a cleaner Player redirection.

trigger1 = GetPlayerID(5) = Player(5), ID
trigger2 = PlayerID(GetPlayerID(5)), Life = Player(5), Life

LocalScale

While not direct replacements, LocalCoord or Const240p (or another appropriate scale) can be used instead in your calculations.

MajorVersion

MajorVersion was removed in Ikemen GO 1.0. It is equivalent to MugenVersion >= 1.0. You may also be interested in the IkemenVersion trigger.

Rand

The Rand trigger name, which was previously deprecated in version 0.98, has been completely removed in favor of the existing RandomRange trigger name.

RoundState = -1

For better compatibility with Mugen content, the vanilla Mugen RoundState now returns 0 instead of -1 during the post-round sequence, just like Mugen. Dedicated triggers, ContinueScreen, VictoryScreen, and WinScreen, have been added to reliably detect the post-round sequence of a match.

RoundType

RoundType was removed in Ikemen GO 1.0 in favor of the new DecisiveRound trigger. Values returned by RoundType are equivalent to:

DecisiveRound: match ends if player win
p2,DecisiveRound: match ends if the player's opponent wins
DecisiveRound || p2,DecisiveRound: match ends if either of players wins (final round)

TimeLeft

The TimeLeft trigger name, which was previously deprecated in version 0.98, has been completely removed in favor of the existing TimeRemaining trigger name.

Lifebar Changes

[Action]

Spacing

The spacing parameter was changed to be absolute instead of being measured from the end of the message sprite (which caused miscalculations). For this reason, a lifebar made for an older Ikemen version will need an increase in team1.spacing and team2.spacing.

[Stunbar]

By default the stun bar will now work as the other bars, starting from full and emptying as the player loses points. To maintain the previous behavior, the pX.invertfill = 1 parameter can be added.

Stage Changes
