How can I make a AI LOS system with a ray cast if it’s possible?

graceful wharf Mar 18, 2024, 10:00 PM

#

Get pos of the AI and subtract it by the pos of the local player, this makes a raycast point from the AI to the Player at ALL times

#

(Note if it doesn’t work, swap the subtracted pos with each other, I honestly forget which is first but you’ll find it by playing with the math a little bit)

Is the raycast unsynced and how would I add limits to how wide the LOS is?

#

Or if that’s not possible with a raycast what other method would I use?

elfin obsidian Is the raycast unsynced and how would I add limits to how wide the LOS is?

Raycast is local, and Raycast specifically is a line, it isn’t a cone, you can adjust the distance it can travel, but not the width, you’d want to use a sphere cast for that, it’s the exact same as a Raycast but it’s a rounded off cylinder instead of a line

#

I’m confused how would the spherecast widen and how would I stop it from going 360

Sry if it’s a dumb question but I don’t use raycasts and spherecasts much

it would never go 360 unless you specify it to?

#

It has a start pos and a direction to face

#

So it starts somewhere, and then points where you make it point

elfin obsidian Mar 18, 2024, 10:12 PM

#

Yes but how would it widen over distance than?

graceful wharf Mar 18, 2024, 10:12 PM

#

It doesn’t, it’s a consistent size, it isn’t a cone, we don’t have a raycast that is a cone

#

Fairly sure you can make your own with some Vector math, but I’m unsure how you’d do that unfortunately

elfin obsidian Mar 18, 2024, 10:14 PM

#

Oh dang
Do you know anyone that’s good at vector math?

graceful wharf Mar 18, 2024, 10:15 PM

#

I don’t know anyone really lol, you could search for it inside the #1020094893458198578 threads, I’m more than sure there have been others who have asked for a method to make a conecast

@dense loom (sry for ping I can’t delete this message if you don’t like pings) do you know anyway to make AI Line of sight like a cone line of sight?

dense loom Mar 18, 2024, 10:33 PM

#

i havent tried to make anything cone shaped so no

U should search for your question b4 asking

#

Pretty sure this has been asked b4 bc I’ve answered it b4

#

But to answer ur question, you use the Vector3 Dot chip in combination with the Raycast system Truchhi explained

elfin obsidian Mar 19, 2024, 4:29 AM

#

How would I combinate it like what do o connect

pallid glacier Mar 19, 2024, 4:30 AM

#

elfin obsidian How can I make a AI LOS system with a ray cast if it’s possible?

Acos(Vector3 Dot(AI Forward Direction, Direction Of Player)), where Direction Of Player is the direction of the player from the AI, which is Subtract(Player Position, AI Position)
Check if this value is less than or equal to ur desired angle using the Less Or Equal chip. If it is, and the Raycast from the AI to the player is uninterrupted, the player is in the line of sight.

Could you tell me what ports to connect possibly I don’t get what you mean or what to connect to what

Might have to make a reference post on circuit notation bc it takes a while to have to explain the individual ports to connect (I know bc in the past I explained everything in this level of detail)

#

But until then wait for someone else to assist u

Do you think you could connect it in game or is that too much

pallid glacier Mar 19, 2024, 4:39 AM

Unless I just decide to explain it anyways but idk
