MTA Checking is player looking at XYZ

[Spc]

Hey, I'm making a flashbang and i need check, is player looking at XYZ position. For example: The explosion xyz is 0,0,0 and if player camera looks at it, something happens.

Wouldn't it be easier by checking whether the given XYZ within the field of view (on screen)?

getScreenFromWorldPosition will return false if the XYZ is not on screen (or within n-pixels from the edge controlled by the edgeTolerance parameter). You should combine it with isLineOfSightClear or processLineOfSight to check whether the flashbang wasn't occluded by an object or wall.

I used getScreenFromWorldPosition and sometimes the function returns false when i was looking at explosion position, and sometimes function returns float when i wasn't looking at explosion xyz.

I'm using this one:

isLineOfSightClear(playerX, playerY, playerZ, explosionX, explosionY, explosionZ, true, true, false, true, true)

 

Another:

local _, _, playerRotZ = getElementRotation(localPlayer)
local angle = math.atan2(explosionY - playerY, explosionX - playerX) + math.rad(180 - playerRotZ)

if angle < 0 then
	angle = angle + math.rad(360)
end

if math.deg(angle) >= 180 then -- facing of explosion
	-- player flashed
end

 

PlayerX/Y/Z works with camera poses.
