Re: Object recycling tips

I would also assign some variable for the type of object it is(different types most likely have different methods, etc). Then when you need to create a new object run it against the table of objects for that type. If it finds a match then re-init, otherwise create a new instance. All of my objects ...

Object recycling tips

Okay, some of you may have heard that it is a good practice to recycle/reuse unused object instead of creating new one. That approach is easy to implement in Lua since any table can be refilled with new instance values, and in the end you are going to create no excess overhead (except for minimal ut...

Re: Objects table(active/inactive) - removing and adding

Also a note about removing table entries in a loop - you have to count backwards to avoid loop jumps.

Code: Select all

for i=count,1,-1 do
	if objectsArray[i].active == true then
		table.remove(objectsArray,i)
	end
end

Re: [lib] Box2D Helper

Looks fantastic! May i ask, does it support World:queryBoundingBox ? If it doesn't, this is sort of suggestion for you. It could be a neat feature. Idk, like, maybe it should highlight all intersecting fixtures that are in AABB? Because in my practice, sometimes it's cheaper and faster to use this f...

Re: Textured Polygon

In 0.9.0 and newer you can just use a [wiki]Mesh[/wiki], which allows you to draw textured polygons natively. This. And i want to add that as long as user is able to correctly track and calculate UV coordinates, the result will be repeating texture polygon (given that texture has correct setWrap fl...

Re: Multiplayer Help

Because string is basically array of bytes which is easy to work with: to compose on sender side and to process on receiver side using standard string libraries. You can set up communication without using strings and using your own encode-decode format, but your data is going to be a pack of bytes a...

Re: APE (Another Particle Editor) for LÖVE2D

Oh wow, i'm thrilled with that testing gif and the fact that tool is actually is used in someone's project. Great stuff! Although i'm not really fan of games of this kind of genre (just because i've never actually played them before), the apparent amount of work that is put into upcoming project of ...

Spritebatch extension

I don't know if anyone did this already, but in my previous thread i've come with a way to change vertex data of a spritebatch. It allows user to change individual sprite geometry and vertex colors (and change color of already existing sprites), and as a bonus - change sprite drawing order. https://...

Re: Love2D "Serial Port Communication"

As a microcontroller enthusiast i'm interested in this kind of thing. Does it use ffi? Or love script communicates to some other application as client?
