Can the new asset system load assets dynamically?

  Is this kind of what you’re after.

  viewer.mode=STANDARD
  
  function setup()
      folder=asset.builtin.Planet_Cute    -- change folder name
      tab=folder.all
  end
  
  function draw()
      background(0)
      for a,b in pairs(tab) do
          sprite(b,WIDTH/2,HEIGHT-a*50)
      end
  end

  @UberGoober - I tend to use tables with the relevant data in and a path to the source.
  
  Kinda like:
  
  ~~~
  
  pics = {}
  
  path = asset.documents.Dropbox
  For lp =1, #Objects do
  pics[lp] = readImage(Objects[lp])
  end
  
  
  Objects = {
  image1,
  Image2,
  Image3
  }
  
  ~~~
  
  Please ignore poor formatting and incomplete code , just trying to illustrate the loading method I use.

  @dave1707 I don’t think so.

  I want to be able to pass a string to a function and have it use that string to attach a model to an entity.

  Here’s the function I pasted above, but pared down to just that functionality:

  
  function makeAThing(modelString)
      local newEntity = scene:entity()  
      local modelFromString = craft.model(asset[modelString]) <—does not work
      newEntity.model = modelFromString
      return newEntity
  end

  @Bri_G for saving or for loading?

  Sample code?

  This works if you pass the whole name. Create a table with the full names of what you want and pass a selection.

  viewer.mode=FULLSCREEN
  
  function setup()
      scene = craft.scene()
      scene.camera.position=vec3(0,0,-80)  
      scene.sky.material.horizon=color(0,100,150)
  
      xx(asset.builtin.Blocky_Characters.Robot)
  end
  
  function update(dt)
      scene:update(dt)
  end
  
  function draw()
      update(DeltaTime)
      scene:draw()       
  end
  
  function xx(name)
      ch = scene:entity()
      ch.model = craft.model(name)
  end

  Or this.

  viewer.mode=FULLSCREEN
  
  function setup()
      scene = craft.scene()
      scene.camera.position=vec3(0,0,-80)  
      scene.sky.material.horizon=color(0,100,150)
      xx("Robot")
  end
  
  function update(dt)
      scene:update(dt)
  end
  
  function draw()
      update(DeltaTime)
      scene:draw()       
  end
  
  function xx(name)
      ch = scene:entity()
      ch.model = craft.model(asset.builtin.Blocky_Characters[name])
  end

  @UberGoober - for loading. I use it for loading images. I also used it for loading models - when I made the video in The Final Frontier thread. I will be posting a project to load the 8 galaxies from Elite in that thread shortly once I sort out galaxy selection and find a way to export all the assets in the zipped project.

  @UberGoober - are you posting on your phone? Every time I do the tilde reformatting doesn't work. -Android phone. Must use a different character set.

  @dave1707 I don’t think craft.model(name) works in any but very specific conditions, and in the example where xx(name) has a hard-coded path to a specific asset pack, that’s the exact thing I am trying to get around having to do.

  It think I’ve got this now, though. The breakthrough was that, for anything in an asset pack, the pack has to be accessed by brackets too, as in:

  
  
  craft.model(asset.builtin[packName][modelName])
  
  
  

  I am a bit abashed to admit this, but the frustrating thing was that once I figured this out I looked back through my code and found a place where I’d cut-and-pasted code from the 3D Asset Viewer that does this exact thing.

  I was looking at the touch demo you gave me and found that it’s possible to do use string concatenation also because asset returns a string for however deep you go.

  packs = { “Space cute” }
  models = { “Rocketship”}
  
  asset.builtin..packs[1]..models[1]
