SkillSector/scripts/SkillSectorWaypointWrangler.cs

// I guess there's two kinds of waypoints that I want to wrangle.
// 1. Zone based waypoints
// 2. Point to point waypoints

// Zone based waypoints are perfect for rooms full of teleporters / switches / etc.
// Point to point waypoints are perfect for races and leading someone from one end of the map to another. I dunno, like a tutorial.

// Waypoints don't seem to be removable per-client without extensive modifications, so they're permanent.
// While it's possible to swap the clients team to show them different team waypoints, I like everyone being on the same sensor network.

// After a lot of reading scripts, engine source code and Ghidra decompiling, I've ascertained that... we're stuck with a bit of an odd structure.
// While it's true that you can allocate 512 TargetManager targets, HUDTargetList is limited to 32 targets exactly.
// Those 32 targets are split across three categories.
// 1 - ClientTarget::AssignedTask
// 15 - ClientTarget::PotentialTask
// 16 - ClientTarget::Waypoint

// What does that mean for my original intent with this script? Well, it's still achievable... but only by spamming the client.
// PotentialTasks are shown for 2 seconds after they're received.
// The player can show those tasks again by pressing n to summon the task list.
// Instead of trying to train players to press `n` when they want directions/more information... I'll spam them.
// Sending the task every 1900ms means it will arrive well before the last task expires.
// Players will always see a task when they're in the zone, and when they leave the zone, they will expire quickly.
// The oldest task is overwritten, so if someone starts using the chat menu or command circuit to create more tasks, that will still work.
