The formal name would be carbonated beverage

I don’t think “correct” really applies here. “Original” maybe.

I’d imagine you just say the name of the other soda. I don’t say “I’d like a Dr. Pepper soda” after all.

Seems pretty rated to me

It’s literally their jobs to fight back though

I wasn’t suggesting that, I just meant that a theory can be algorithmic while working with probability distributions rather than deterministic values.

If they need to call me it’s either actually complicated, or (much more likely) they haven’t spent enough time to refine their idea to where they could just write it down.

… You speak as if you know what you are talking about, but you clearly do not.

You are constantly jamming into the surface and doing a whole bunch of collision checks to basically scrape the player across the surface… …because you have to keep doing those checks in a loop untill you determine the obstacle is finally cleared, and then switch back to unrestricted or ‘normal’ grapple-movement.

Unnecessary “…”, and no, you don’t loop the check until the obstacle is passed any more than you would “loop” the player’s ordinary movement. As normal, each tick you attempt to move the player forward some distance. If there is an obstacle in the way, they’ll move less distance, which is fine-- this prevents them from rocketing up walls if they’re slightly below a target grapple point beyond the wall, as in the below scenario.

You have to keep doing 3d vector collision mesh check calculations for the whole time the player is being ‘scraped’… because you don’t know when to switch ‘perpendicular movement only’ mode off, otherwise… so this is inefficient.

What would be more efficient? Depending on how the game physics work, the player’s collision mesh is probably a capsule, simple box, or sphere. It’s really not that expensive to add this check; the player is presumably already doing collision checks using their mesh every tick for like, standing on the ground and touching walls.

Assuming this is a 3D environment… there’s no way you can just totally null out one dimension of the movement vector unless the player is perfectly perpendicular hitting a perfectly perpendicular surface.

If your level design is any degree of complex, with objects beyond basically perfect boxes that are all perfectly orientes to the world grid… and if the player is allowed to rotate… this doesn’t work, your calcs still always involve 3 dimensions.

What you’re saying might work in a 2D game… or I guess 2.5D, maybe?.. but it wouldn’t work in a 3D game.

When did I ever say that you would accomplish this effect by nulling out one component of their movement vector? That idea is a fabrication of your own delusions. It’s pretty easy to do a mesh collision check, get the normal of the tri the player collided with, and use that to remove all the player’s movement in that direction. This is probably already part of the engine’s physics calculations anyways!

[the 3d pathfinding idea]

This could work, especially if the grappling hook is one of those ones where gravity stops affecting you (could be good for gameplay, that’s valid). But to construct this path in a realistic manner, you would need to do similar calculations to what you’re saying are inefficient, except all at once instead of spread over multiple frames. If you simplify the pathfinding checks to make the movement simpler, you could in most cases do the same thing with the player collision checks. Depends on how you implement it though I suppose. Too specific to cover all cases in a general discussion.

You have an odd definition of ‘realistically’.

It is realistic that if I grapple into a surface I will move a shorter distance than if I was grappling freely, yes. This is true without friction etc. as well. Think of the extreme case: grappling directly downwards into the floor, in which case I would not move at all.

Spheres tend to be the absolute worst objects to use in a collision mesh or hull, because they are comprised of far, far more tris or rects than a box.

LMAO are you kidding me??

First of all you could do a check using a proper sphere rather than a mesh with tris. This can actually be faster than using a box-- eg. checking if two spheres (or a sphere and a point) collide is literally just a distance check compared to their combined radii. I bet even sphere-tri collision is easier than tri-tri, although my game engine knowledge doesn’t extend far enough to say for sure in that case.

There is a reason hitboxes… are called ‘boxes’.

They’re called that because boxes are common, not because they’re the best.

I think what you are trying to describe is a common concept in games where many objects that are basically… clutter, vegetation, extra fluff… they just do not interact with the player collision mesh/hull at all, for many parts of the engine/game. […]

This entire line of critique is invalid because I wasn’t saying that at all. I’m saying that as a consequence of the collisions, they could pass around an obstacle; not that they could go through it. A rock under the player as they grapple sideways would push them upwards and slightly away due to the angle of the collision, and they could then continue moving sideways as before.

Again this ‘solution’ of yours (which just entirely abandons the concept of just not colliding with small objects, which you literally just described) […]

How on God’s green Earth could you possibly, after I literally just described the precise mechanism by which the player would interact with small objects, still believe that I meant they should simply pass through them??? Maybe if you read the whole post instead of replying to each sentence individually you would’ve made that connection. Yes, I see the irony; I did read your whole post first though.

[…] just causes the problem the original comment was trying to avoid: having to do a whole bunch of collision calcs every time any obstacle is encountered.

If you apply the grapple as a force it’s literally the same collision calcs the player makes every single tick. If you can’t due to engine/game/etc. limitations, it’s still not that much extra collision calculation.

… You speak as if you know what you are talking about, but you clearly do not.

Have you ever actually mocked up a 3 physics scenario in a game engine, or modded an existing game in a manner that is very reliant on or interactive with its physics engine?

Try me. I am extensively aware of the way physics is typically handled in games. I will admit I don’t often use game engines, because I usually try to make 2d games from scratch and implement my own simple physics. But yes, I’m aware of how 3d engines handle physics as well.

Ow that one hits me right in the briefcase

Are you implying that’s wrong or you just don’t know

That sounds mad, you have to not care

Seriously?

The analogy to the gravitational force isn’t on point; there’s a lot more to be said about how magnets tie to into E&M more broadly, compared to gravity.

Yeah, a proper answer would need to dive into how it relates to electricity for sure

QM is entirely algorithmic, it just operates on values that are of type “Probability Distribution”

That interview answer always seemed like a cop-out to me. You could make a comparison to gravity to explain how magnetism “just is”.

You could plausibly implement some physics to deal with it. If the player is moving into a surface, move them along the part of their grapple movement component that’s perpendicular to that surface. This will allow them to slide along walls/floors/ceilings realistically. For the case where they need to move “through” a small object, you could treat their collision as a sphere and have it collide with the object; for small objects, this could let them pass by. Eg. for grappling sideways over a small rock on the ground, their point of collision would be mostly below them and a bit to the right, but they’re being pulled mostly straight to the right, so they would move perpendicular to the point of contact and move up-right over the rock, then continue their grapple path. Depending on your game’s physics system there are other solutions, but for a typical game engine, that should work well.

Having taken an ML class, with some of my college notes I could do this and “understand” it… but the weights would still be a black box. AI training is black (box) magic.

The location that the player is visually interacting with would be different, but the world wouldn’t know that. Eg. in a cutscene, the player reaches out and touches a button on a control panel. If the player’s X is flipped, their left hand will be further left than their right hand, and will miss the button visually as they go to press it. Asymmetrical animations might also be fucked, ie. sidestep/jump right normally extends the left leg for leverage, but now their right leg would push off visually and they would still move right.

Really? I didn’t know that, his pedophilia is more well-known I guess. Thanks for informing me. Either way, you’re allowed to bring up new topics in a conversation.

I got a bit mixed up in the thread, someone had mentioned abusive parents being exempt but it looks like that’s a Germany thing.
