How can I spawn in a block on a specific layer?

Don't you just do this?

Code: Select all

local myBlock = Block.spawn(number blockId, number x, number y)
myBlock.layerName = "myLayerName" --this?  
myBlock.layerObj = Layer.get("myLayerName") --or this  (or both?)
Given, I've never needed to spawn any blocks. That code is just what looking at the API page for 10 seconds got me.

Aren't layerObj and layerName read-only though? That's what the wiki says at least

You can define the layer as:

Code: Select all

local myLayerName = Layer(#)
Replace number with the number the layer is in the list. (Default layer is 0.)
myLayerName also shouldn't be in quotes since it's a variable

No. What S1eth wrote is correct. And I think you can write to layerName and layerObj.
layerName requires a VB6Str (String layername)
layerObj requires the layer object. Essentially what you wanted to assign to layerName in your post.

Hey guys, I'm a little curious, is there anyway to make an NPC behave as if it's in water, even if it's not? I mean the entire specific NPC population, not just a single one (I can do that with attach water layer). For example, a generator of slow rexes.

Don't be in any rush to respond. It's not something I'm working on right now. I've just got an idea for a level in the future.

NPC.underwater. You can use NPC.get() to grab all NPCs

Using unicode symbols in variable names is an AWFUL idea. That may well be at least part of your problem.

You can define the layer as:

Code: Select all

local myLayerName = Layer(#)
Replace number with the number the layer is in the list. (Default layer is 0.)
myLayerName also shouldn't be in quotes since it's a variable
No. What S1eth wrote is correct. And I think you can write to layerName and layerObj.
layerName requires a VB6Str (String layername)
layerObj requires the layer object. Essentially what you wanted to assign to layerName in your post.
I tried it, and as Nerx said, both of these are readonly.
A newly spawned block returns "Default" as its layerName.
So, since these are readonly, and the Block.spawn funtion does not have an overload which accepts the layer as argument, it should be impossible to spawn a block on any layer other than "Default" until someone writes another Block.spawn function.

Maybe the Block:mem function can be used to circumvent this if you know the memory address of layerName and layerObj.

As per http://wohlsoft.ru/pgewiki/SpriteOverride_%28class%29 you shouldn't be replacing the background[24] itself.

Graphics.sprites.background[24].img = myLuaImageResource

Use "MECHDRAGON" or something. Unicode symbols can seriously break your code.

Wouldn't wrapping the replacement lines into a for loop be more efficient/readable/easier to edit? Something like:

Code: Select all

local tableOfBGOSpriteIDs = {1,3,6,8,99} --table of image IDs to import

for _,v in ipairs(tableOfBGOSpriteIDs) do
   local imageFile = Graphics.loadImage("MECHDRAGON.nba" .. tostring(v)..".png") --if you need the imageFile reference later, make imageFile a table outside the loop and set/get imageFile[v] inside the loop.
   Graphics.sprites.background[v].img = imageFile
end

Yes it would.

In future, Mechdragon, if you find yourself needing to make a bunch of variables for a similar thing, particularly if you're finding yourself naming them something like: "name1", "name2", "name3", etc., consider whether or not it would be easier to just use a table.

Don't you just do this?

Code: Select all

local myBlock = Block.spawn(number blockId, number x, number y)
myBlock.layerName = "myLayerName" --this?  
myBlock.layerObj = Layer.get("myLayerName") --or this  (or both?)
Given, I've never needed to spawn any blocks. That code is just what looking at the API page for 10 seconds got me.
You can define the layer as:

Code: Select all

local myLayerName = Layer(#)
Replace number with the number the layer is in the list. (Default layer is 0.)
myLayerName also shouldn't be in quotes since it's a variable
No. What S1eth wrote is correct. And I think you can write to layerName and layerObj.
layerName requires a VB6Str (String layername)
layerObj requires the layer object. Essentially what you wanted to assign to layerName in your post.
The reason why the layerName is read-only is because it would require to update the visiblity flag of the object (If the item is visible, but the layer is hidden, then the item must be hidden too)

That's... kind of a poor reason in my opinion. You could quite easily set it up to automatically update the visibility of the item when you set the layerName value, or you could just add a note on the documentation.

Besides, I believe you can set the layer name via mem calls anyway.

I know that it is a poor reason, and it will change. I already put it on the wishlist so I won't forget it.

I should learn more about tables.
