I am making a building system based on the classic trowel. I need to make this selector rotate with the player only by 0,90,180 degrees etc. (as if snap was used).
Here’s how it should look like
But if I turn around, it won’t change (should be in front of the player)
Code:
Tool.Equipped:Connect(function()
if not Tool.Enabled then
return
end
if buildsBuilt >= 15 then
return
end
if Tool.Parent.HumanoidRootPart then
equipped = true
temp = selector:Clone()
temp.Parent = workspace
while Tool.Enabled and temp and equipped do
if temp then
temp.CFrame = CFrame.new(Tool.Parent.HumanoidRootPart.Position+Vector3.new(0,0,-5), Tool.Parent.HumanoidRootPart.Position)
task.wait(0.0001)
end
end
end
end)
What should i add or remove to make this possible?
A simple solution would be to check the rotation of the character based on the world axis and of it exceeds 45 degrees every time the player rotates then the selector will also rotate.
if characterRotation > 45 degrees and characterRotation < 135 degrees then
selector.Rotation += 90 degrees
end
this is just a pseudo code
Then you can just do the same for the other quadrants
if characterRotation > 45 degrees and characterRotation < 135 degrees then
selector.Rotation += 90 degrees
end
if characterRotation > 135 degrees and characterRotation < 225 degrees then
selector.Rotation += 90 degrees
end
if characterRotation > 225 degrees and characterRotation < 315 degrees then
selector.Rotation += 90 degrees
end
if characterRotation > 315 degrees and characterRotation < 45 degrees then
selector.Rotation += 90 degrees
end

selector.Anchored = true;
local function selectorFollowsPlayer()
selector.CFrame = CFrame.new(playerHRP.CFrame.LookVector * 5) * CFrame.new(Vector3.new(0,1,0)) * CFrame.new(playerHRP.CFrame.Position);
end
local function rotateSelector()
if playerHRP.Orientation.Y > 45 and playerHRP.Orientation.Y < 135 then
selector.Rotation = Vector3.new(0,90,0);
end
if playerHRP.Orientation.Y > 135 and playerHRP.Orientation.Y > -135 then
selector.Rotation = Vector3.new(0,180,0);
end
if playerHRP.Orientation.Y > -135 and playerHRP.Orientation.Y < -45 then
selector.Rotation = Vector3.new(0,270,0);
end
if playerHRP.Orientation.Y > -45 and playerHRP.Orientation.Y < 45 then
selector.Rotation = Vector3.new(0,0,0);
end
end
RunService.PreRender:Connect(function()
selectorFollowsPlayer();
rotateSelector();
end)
The blue is the checks if there are anything in the way so it can snap the selector into place.
Keep in mind you if you want to check if the tiles in front of the player are available then your going to need a lot of code(e.g. buildings, obstacles, etc…) and if there is elevation in the terrain as well you need to raise the position by the tile size(so that its square) or you can create a height map.
Honestly tough work if your going to implement any of this but good luck though, the code I gave in the comment above this is the best I can do for you.
