Re: How to reference Bump's "bounce variable
When you are looping through the collisions, you're accidentally using the wrong variable to access the list of collisions: for i = 1, len do if cols[v].bounce.x > v.x then -- the '[v]' should be '[i]' -- ... end end In addition, it might be wise to first check that the collision response is a bounc...

Re: Fixed screen in Menori
I'm not familiar with Menori, but I presume you can render its output (and any other things you need) onto a canvas. You can then figure out the biggest rectangle that respects the desired aspect ratio, and then render the canvas to the screen with those dimensions.

Re: Copying a file from a local directory to the LOVE save directory
You could potentially use os.execute, and run some copy commands to transfer those files over. These commands may be platform specifc, like using robocopy on windows. This method may flash a command prompt on users' screens, but if you mean to do the file transfers as a one-time thing (eg. when firs...

Re: How do I make a value absolute?
If you mean to take the absolute value of a number, the function you're looking for is math.abs:
However, if you mean something like a constant value, ie. a value that can not be changed, that's a bit more complicated topic.
Code: Select all
local value = -2
value = math.abs(value)
print(value) -- prints 2

Re: I have a question about how lua works in general
Well, as the error warns you, you can not index a function. To illustrate it, consider this minimum example: local function myFunction() end -- an empty function that does nothing myFunction() -- ok myFunction.someValue() -- error, can not index a function The same goes for situations, like trying t...

Re: I just accidentally found a literal zip bomb for the ram in love
While it's surprising that your example creates so much garbage, it's not also not particularly special, now is it? There are many ways to fill up RAM (excessive table creation, loading a bunch of assets into memory), force heavy CPU loads (just modifying love.run slightly could do), or cause excess...

Re: Need help understanding bump.lua and also why my bullets act this way
Right, I think I intended to do that modification as well (either doing what you did, or assigning to a local variable), but must've slipped my mind.

Re: Need help understanding bump.lua and also why my bullets act this way
I believe the issue stems from the following: for i, bulletToRemove in ipairs(bulletsToRemove) do world:remove(bulletToRemove) table.remove(activeBullets, bulletToRemove[i]) -- this line here end I'm reasonably sure bulletToRemove[ i ] will just evaluate to nil in this context, which means that tabl...

Re: Having trouble with bump when different objects are on the screen
You are experiencing this behavior because you are using the world:check function, as opposed to the world:move function. -- change this... local actualX, actualY, cols, len = world:check(player, futureX, futureY) -- to this local actualX, actualY, cols, len = world:move(player, futureX, futureY) As...
