Sven Co-op Semiclip is an AMXX plugin that provides exactly what it says. This new version of Semiclip plugin works after all updates broke the previous methods.

• Due to the great amount of engine changes Svengine suffered over the time, the older Metamod implementation broke and apparently there wasn't a way to fix it.
• anggaranothing released a new version of Semiclip using Sven Co-op's own scripting language, AngelScript. However, there are several problems that affect the functionality and make playing with this plugin more a hassle than an improvement:
  • This implementation uses groupinfo, making the players invisible when nearby.
  • This may also break custom maps that make use of this.
  • AngelScript doesn't have AddToFullPack, so it's actually impossible to render players using AS alone, you could in theory "fix" this by using AMXX.
  • Sven Co-op made a small change that automatically unstuck colliding players, so if you try to boost someone there are high chances that you will be sent flying away.

• This plugin uses Orpheu and hooks directly in the function responsible for allowing collision between entities. AddToFullPack is also implemented, so players will not rubberband when going through each other.
• Boosting between players feels extremely smooth, almost native. Although it still a little trickier to reach higher places, because you need to jump before the player below stands up or else you'll fall through.
• It gives us more liberty on a easy to read code, it will allow us to implement more features like PVP support on maps that support it. (Which is currently a to-do!)

• Orpheu
• Updated Orpheu signatures for Svengine (click to get the latest version of the signatures I made)

• amx_semiclip_enabled
  • Enables the plugin. Takes effect on map start. Default 1.

• Th3-822
  • Helped me a lot with Orpheu and explaining me how the game works internally, and pretty much this plugin wouldn't be possible if it wasn't for him.
