Help with SetPrimaryPartCFrame in a model?
The script is:
01 | local part = script.Parent |
02 | local model = workspace.YOOHOO |
03 |
04 |
05 | function nicshere(onClick) |
06 | workspace.THISNIGZ.CanCollide = false |
07 | model:SetPrimaryPartCFrame(-14, -8.5, -129.5) |
08 | wait(.1) |
09 | model:SetPrimaryPartCFrame(-14, -8, -129.5) |
10 | wait(.1) |
11 | model:SetPrimaryPartCFrame(-14, -7.5, -129.5) |
12 | wait(.1) |
13 | model:SetPrimaryPartCFrame(-14, -7, -129.5) |
14 | wait(.1) |
15 | model:SetPrimaryPartCFrame(-14, -6.5, -129.5) |
Before I set the script to model:Set.. it was model.Set... and I got an output error of "expected model: calling member function" and now I'm getting "Unable to cast double to CoordinateFrame"

"Cast" means "convert". A "double" is a (double-precision) number.
The error is saying that it wanted a CFrame, but got a number.
You have to make a new CFrame, and then provide that, instead of just giving numbers:
1 | model:SetPrimaryPartCFrame(CFrame.new(-14, -0, -129.5)) |
but wait -- before you go and change that for every line -- use a loop!
There's a principle of programming called don't repeat yourself. Notice how your code is the same thing over and over? That's a bad thing. You can save yourself a lot of work and allow you to do more by eliminating repetition.
A for loop is designed exactly for this. The only thing that is changing is going from -8.5 to 0 by 0.5. It's really easy to write that into a for loop.
1 | for y = -8.5, 0, 0.5 do |
2 |
3 | end |
Read this as for each y from -8.5 to 0 by steps of 0.5 ....
1 | for y = -8.5, 0, 0.5 do |
2 | model:SetPrimaryPartCFrame(CFrame.new(-14, y, -129.5)) |
3 | -- notice how I use "y" in the CFrame |
4 | wait(.1) |
5 | end |
