Yes, that is the way system.active is meant to be used. It should be documented in the API somewhere (hopefully).

While tiny-ecs has an API and a demo, it doesn't have much in the way of a tutorial. Maybe I should make one.

This is quite awesome and useful.

Instead of setting the jump counter to two when the character is on the ground, always set it to one (regardless of double jumping). Right when the character jumps, check if the character starts on the ground and can double jump, and if so, increment the jump counter to two before decrementing it (o...

Just an update, I've now added resources and function serialization to binser.

You have the basic idea. In general, this becomes easier when you move most of the code into a function called once a frame, like love.update. Much of the code in player.jump, like the movement code, should probably go into a function called player.update(dt) or player:update(dt). Your jump_mode fun...

I agree with most of what's already been said, mainly not to optimize before it's an issue, but pretending that code doesn't ever need to be optimized is just wishful thinking. Poorly thought out code will be slower, and poorly optimized code will be faster in all of the wrong places. First, be awar...

And of course, I didn't mention one of the more extensive implementations tailored to LOVE. Yeah CPML is pretty awesome and works in tandem with LOVE3D and love 0.10.0. btw, shakesoda, the IQM loader is awesome! Almost used it and LOVE3D for Ludum Dare, but went with pre-rendered 3d instead. I didn'...

Filters do cache results for preformance reasons; systems that iterate through entities only iterate through a sequence when they update. Unless you add or remove a lot of entities every update cycle, there is very little overhead. In fact, a vanilla 'tiny.system' doesn't even iterate through it's e...

Weregoat https://love2d.org/imgmirrur/kc5kLk1.png Not Heregoat or Theregoat, but Weregoat. Play as John Courage in the town of Nowhere and savage your fellow townspeople. I'm really tired now, but everything worked out ok. There are a lot of things I implemented but never ended up using like a dial...

The game title made me chuckle.

I'm still working on my ludum dare entry. I'm actually pretty jealous that you're already done.
