simpleLayerMovement.lua - For all your custom layer movement needs!

[MrDoubleA]

This is a library which allows for you to simply create complex layer movement. You can download it here! For examples and how to use, see "Loading & Examples".

Loading & Examples: show

To load it, simply put this in your luna.lua file:

Code: Select all

local slm = require("simpleLayerMovement")

Here are some examples:

Circular Movement

Code: Select all

slm.addLayer{name = "move 1",movement = slm.MOVEMENT_CIRCLE,speed = 64,verticalDistance = 1,horizontalDistance = 1.5}
slm.addLayer{name = "move 2",movement = slm.MOVEMENT_CIRCLE,speed = 32,distance = 0.5}

Looping Movement

Code: Select all

slm.addLayer{name = "move 1",verticalMovement = slm.MOVEMENT_LOOP,verticalSpeed = 2,verticalDistance = 320}

Cosine Wave Movement

Code: Select all

slm.addLayer{name = "move 1",speed = 96,horizontalMovement = slm.MOVEMENT_COSINE,horizontalSpeed = 64,horizontalDistance = 1}

Points Movements

Code: Select all

slm.addLayer{name = "move 1",movement = slm.MOVEMENT_POINTS,speed = 1,points = {vector(64,32),vector(96,96),vector(-96,96),vector(-64,32),vector(0,0)}}
slm.addLayer{name = "move 2",movement = slm.MOVEMENT_POINTS,speed = 3,points = {vector(48,-48),vector(96,0),vector(0,0)}}

This is really cool. Well done!

Finally we won't have crazy jank moving layers. This will be very useful.

Just wanted to say that I found this library very helpful. Thanks for making it!

I don't understand how to use the script =(. I wrote local slm = require("simpleLayerMovement") in my lua file from the level. Packed the lua file from the script in my level folder. I don't understand where and how I should now register my layer from the editor. Can someone explain that to me in a bit more detail

You cannot use it from the editor itself. You need to add some extra code to your luna.lua file (like what's shown in the "examples" part of the post).

I know how to address layers from the lua file. I have read the code several times and do not understand where to place my layer. Is it possible to upload a small demo level where i can see how it works? maybe?! :/

All you need to do to get started is copy and paste the examples into your luna.lua file, and change the names. If you are having trouble, you can send your current code to let me see what's wrong with it.

The luna code is trying to find the layers in other levels that don't have these layers, creating an error. How do I isolate the code to just the one level if the examples are to be pasted in the global lua file?

Don't put it in the global lua file, and use the level's lua file instead.

Really useful. LIke your example screenshot already shows, it is better than npc-106 (SMB1 elevator).
But how exactly did you create this "multiple elevators"-effect (no idea how to call it) without interruption?
(so from SMB 1-2 near the end of the level)

Code: Select all

slm.addLayer{name = "move 3",verticalMovement = slm.MOVEMENT_LOOP,verticalSpeed = 2,verticalDistance = 3500}

is only for one of them, if you copy one of these "block-units" with that layer and place if offset than the other "block-unit" will also move only 3500 units.
I could make a lot of copies but at some point all of them have went through and it would take some time, until it does repeat again.




Can you tell me what to do?

Is it possible for Poins layer movement to change speed between vectors, so we can have simple crushers like in this gif? Same question goes to looping vectors.

Damn janky vanilla layer movement.
