I have a question about raycast, namely: how to make raycast move to the mouse position, but on the Y axis, and X, Y depend on the position of the raycast starting point. To make it clearer: let’s say the starting point of raycast is the right hand of the player (character), raycast is directed to the mouse position (as in shooters), but only along the Y axis, and the X, Y axis depends on how the player is rotated. (if it’s still unclear, I’ve drawn a diagram:)
local function FIRE(plr,Mouse_Position_Y)
local origin = workspace.Part
local beam = origin.beam
local att1 = origin.Att0.Att1 --Att0 is the beginning of the beam, and Att1 is already the end of the beam.
local params = RaycastParams.new()
local deriction = Mouse_Position_Y.Unit * 300
local result = workspace:Raycast(origin.Position,deriction,params)
att1.CFrame = CFrame.new(deriction, origin.Position)
end
local function Mouse_Position_Y()
local mouse_pos = game.Workspace.CurrentCamera:ScreenPointToRay(game.Players.LocalPlayer:GetMouse().X,game.Players.LocalPlayer:GetMouse().Y)
return mouse_pos.Direction.y
end
local plr = game.Players.LocalPlayer
plr.CharacterAdded:Connect(function(character)
local root = character.PrimaryPart
root.Touched:Connect(function(hit)
FIRE(plr,Mouse_Position_Y())
end)
end)
Thank you in advance for your help!
I would recommend that you use a raycast to get the position of the mouse pointer on the surface in the world.
This can be done by using a RaycastParams object, and then use the Raycast method. local rayCastParams = RaycastParams.new()
rayCastParams.FilterType = Enum.RaycastFilterType.Blacklist
rayCastParams.FilterDescendantsInstances = {workspace.Part}
local ray = workspace:GetCurrentCamera():ScreenPointToRay(
Vector2.new(mouseX, mouseY),
rayCastParams)
local hit, pos = workspace:Raycast(ray.Origin, ray.Direction, rayCastParams)
This will return the point where the mouse cursor is on the surface.
This is the method I use to get mouse coordinates in 3D space, and it works well.
