How do you make an ai collide with walls?

[lilac vortex]

I'm not using rec room AI It's just an object that follows the closest player

[eager hornet]

You could make the object physical

[lilac vortex]

its too much ink thats the issue

Does an invisible collision not work? Or am I just stupid?

[lilac vortex]

it probably does but then the ai wont go to the players it will continuously try go through a wall

[lilac vortex]

i don't know what cv2 to use when it says
if(Vector3.Angle(temp,forward)<90f) this.escapeDirection = temp;

[torn hearth]

I’m still trying to figure it out too this is just what people have been using

[lilac vortex]

oh ok cheers

[torn hearth]

Also if you just want the ai to stop at walls and don’t care abt pathfinding just have a trigger volume and if objects in it are greater than( however many objects are on the ai) then it stops

Also make sure they reverse away from the walls or they’ll get stuck there

Man I haven’t done this in a while lol

[lilac vortex]

ye i also need pathfinding so it doesn't always follow the player

cheers for the help

Vector3.Angle function calculates the angle (degrees) between two points (vectors). The 90f means the number 90, as a float. The ‘temp’ value is calculated earlier in the code and forward is as well. The recreate Vector3.Angle with cv2… see attachment. I’ll pull up my in game version shortly.

[lilac vortex]

oh

cheers

The min/max chips are redundant, but they will eliminate rounding accidents due to floating point operations. They can likely be eliminated to save some heat

[lilac vortex]

i also just tried the whole circuits but i think i have to of done something wrong let me get a video and show what happens

[sick belfry]

The algorithm is far from perfect, but I think you may have an error somewhere for it to make that poor turn away.

[lilac vortex]

probably the angle thing

[sick belfry]

This is what I have after translating that algorithm to cv2, with some minor modifications.

[lilac vortex]

does it fully work

[sick belfry]

It works as well as the algorithm allows it too, but it isn’t a very intelligent algorithm. It can’t navigate too complex settings

[lilac vortex]

oh fair

[sick belfry]

My bot navigates around most walls to get to me. But some wall patterns it goes back and forth.

[lilac vortex]

that doesn't matter to much tho as it still works

i just got it kind of working but it some how escaped when there is no hole

[sick belfry]

I think it might be beneficial to use spherecast instead of Raycast.

Enemies have size to them, but Raycast checks for a single point of access, not an area

[lilac vortex]

thats fair

[lilac vortex]

how did you reverse the vectors

bcs i scaled mine by -1

but i don't know if thats how to do it

[lilac vortex]

some of the walls aren't colliding with it

and somehow it rotates

upside down

[sick belfry]

I think scaling it by -1 will work, but I instead multiplied it by a vector of -1, -1, -1

What is your marginCollision value set to?

[lilac vortex]

2.2

[sick belfry]

Your step might be too large. You are taking large steps. Would need to see the circuitry tho

[lilac vortex]

alr

give me like 10 minutes

[sick belfry]

In the top right, there is an add chip. One of the values goes down-left out of view. What is it
