mouse.Hit problems with an isometric camera

[kottzj (kottz)]

Hallo!

I have started to work on a game utilising an isometric camera.

I want the game to be pretty mouse influenced eg: You attack where your mouse is; Move towards where your mouse is; etc.
The problem I have encountered is that mouse.Hit doesn’t really work properly when the camera is in a isometric perspective.

It may be that the mouse.Hit doesn’t register correctly on big distances from the camera, since the only way I could replicate an orthographic-like perspective was to move the camera really far, and then make the field of view really low.

Using this script I am now trying to rotate the player towards the mouse:

local mouse = player:GetMouse()
	
humanoid.RootPart.CFrame = CFrame.lookAt(
	humanoid.RootPart.Position,
	Vector3.new(
		mouse.Hit.Position.X,
		humanoid.RootPart.Position.Y,
		mouse.Hit.Position.Z
	)
)

This works wonderful when the isometric camera is not enabled but as soon as it is it gives me this result:

The red block is moving where the mouse.Hit returns, it’s obviously not where the mouse actually is

I have even tried to shoot a ray from the camera to the mouse, and then get the closest points from the ray to the HumanoidRootPart:

local mousePos = game:GetService("UserInputService"):GetMouseLocation()

local mouseRay = workspace.CurrentCamera:ViewportPointToRay(mousePos.X, mousePos.Y)
local closestPoint = (mouseRay.Origin - humanoid.RootPart.Position) - (mouseRay.Origin - humanoid.RootPart.Position):Dot(mouseRay.Direction.Unit) * mouseRay.Direction.Unit
 
local virtualMousePosition = humanoid.RootPart.Position + closestPoint

I really don’t know how to fix this and I would hope for some sort of feedback, thanks!

Mouse.Hit is not compatible with isometric cameras. One possibility is to switch the stepping method, but that might cause stuttering. You should raycast to your desired point instead.
