Lerping
https://www.lukeko.com/33/lerping 0Using a method known as linear interpolation, often referred to as lerp, you can position a CFrame between two points. For instance, the following code positions the redBlock part directly between the greenCube and cyanCube parts, using a value of 0.7 to place it 70% of the distance away from the green cube.
local redBlock = game.Workspace.RedBlock
local greenCube = game.Workspace.GreenCube
local cyanCube = game.Workspace.CyanCube
redBlock.CFrame = greenCube.CFrame:Lerp(cyanCube.CFrame, 0.7)
To animate this smoothly use a loop
local redBlock = game.Workspace.RedBlock
local greenCube = game.Workspace.GreenCube
local cyanCube = game.Workspace.CyanCube
for i = 0, 1, 0.1 do
wait()
redBlock.CFrame = greenCube.CFrame:Lerp(cyanCube.CFrame, i)
end
