Hello all, I tried googling this before coming here, and did not find anything. Is there a way to determine if the player is facing a Ped? I am trying to create a RageUIMenu that becomes visible when the player is standing within 5m of a ped, and is facing them. I have the menu pretty much coded, just working on the Visible logic. Any and all help is appreciated!

I have used this code before to find the difference in heading between two entities:

float headingDiff = MathHelper.NormalizeHeading(object2.Heading - object1.Heading);

So you would want to check that the heading diff was about 180 (give it some +/- range), then also check your distance

Thanks man, I appreciate all your help!

Depending on your needs, the following natives might also be helpful:

 

IS_PED_FACING_PED

_CAN_PED_SEE_PED (I believe this actually checks whether ped A has received an event that ped B has been spotted)

HAS_ENTITY_CLEAR_LOS_TO_ENTITY

HAS_ENTITY_CLEAR_LOS_TO_ENTITY_IN_FRONT

 

The last two are more expensive than the other ones as they perform a proper raytrace (e.g. buildings between two peds are taken into account which is not the case for heading checks).

So something like this? The documentation on this i very limited

 

if (NativeFunction.Natives.IS_PED_FACING_PED<bool>(player, p))
{
  // Logic
}

It takes one more parameter, the angle to check as a float.
