Sonic Advance 2: Boostmentum 2.0 - Big Rework (Aerial Preservation & More!)

---

[NEW]
The first stage designed specifically for Boostmentum has been released!
Check out Nu Angel Island Zone by The BIG DOG!

[INFO]
This mod is based off of the Sonic Advance 2 boost and is also a momentum mod.

Unlike the modern Sonic boost where you just press a button, instead you have to earn your boost! You get it by either charging up from sustained speed, or from huge speed increases (slopes, etc.).
This mod rewards players who can run fast without stopping, so there's a lot of skill involved in keeping your boost active. The better you get at fast-precision platforming, the more you'll get to utilize this mod!

Boosting by itself won't give you crazy speeds. You need to combine it with momentum gain!
Try some custom stages out that have big slopes to take advantage of this.
This mod works best on these custom levels. I've included a list of some I recommend down below.

This mod is intended for characters that do not have their own dash/ boost mode, as it functions differently.
Of course, you can use it with whatever character you want in whatever level!

Lemme know if you enjoy using this!

[HOW TO ACTIVATE]
There's two ways.
1. Keep running and don't stop! Your boost will charge up and activate, just like in Sonic Advance 2.
2. Get huge speed! Roll down a slope, whatever it takes! This activation method is inspired by the old fan game Green Hill Paradise: Act 2.

While boosting, you will not have to meet as high of a speed requirement to maintain it.
There's also a small grace period should you bump into things. You just gotta keep your speed up!

[BOOSTING EFFECTS]
• Subtle speed boost
• High acceleration
• Increased momentum and speed preservation
• Sonic Advance 2-like boost visuals with sound FX (not Modern Sonic boost sounds)
• Damage enemies
• Water running
• Break spikes, monitors, walls, etc.

[COMMANDS]
• boostmglobal (on/ off) - default: on
This enables or disables boosting. Only the server/ admin can use this.
• boostmextreme (on/ off) - default: off
This enables extreme mode. Only the server/ admin can use this.
This mode is not recommended, but its an option for those who just want more speed.
• boostm - default: on
This enables boost mode for just the player. Anyone can use this. This means if you join a server with the mod and don't like it, you can switch it off. Also handy for disabling it when playing certain characters.

[RECOMMENDED MODS]
• Nu Angel Island Zone
• Footsteps
• Speedometer
• ChrispyChars
• Basically any good custom map plays well with this mod.
OLDC 2021 Part 2 is a decent place to start and here's a list of several that I thought played well:

[INCOMPATIBLE MODS]
• Momentum mods other than CrossMomentum (Xmomentum is supported but breaks water running)
• Level mods that use momentum scripts
• Spring Lock
• Halfpipe Utilities
• Modern Sonic
• Characters with their own boosts
• Characters with dash modes may be compatible, but not flow properly

[FOR MODDERS]
If you wish to use my code in your own work then you'll need to ask me first as well as credit myself and whoever worked on the parts you use. This mod shouldn't be re-posted on this site or on any others in its original state or a modified one without my permission.
Just private message me what's up and I'm sure we can work something out, as I'm happy for my work to help you in your own projects.
Personal use edits are allowed, though. For example, changing the sound effects or speed values - you just can't re-release those on this website or any others and you need to keep Boostmentum in the name. For example, "Boostmentum_v2.0-MySpeedEdit.pk3". You also need to keep the original credits inside the pk3, though you can add your own to list your changes if you want.

[CREDITS]
• Star as the creator
• BIGDOG for helping with some of the trickiest parts, testing, providing feedback, and recording clips with me for the trailer. This mod wouldn't be as good without his awesome help!
• Delf for his Momentum mod and a little bit of his Boost code, which helped start this project!
• AurumMighty for part of his Speed Effects to get the white lines for the Sonic Advance 2 visuals!
If there's anyone who assisted them and also wants credit then just lemme know.

Special thanks to all these guys. They're awesome modders and I recommend checking out their work.

[MOD SUPPORT]
If you wish to add support for Boostmentum by disabling a certain feature when its active, then all you have to do is include:
if player.boostmentum then (your momentum tweaks, or whatever) = false end
