They elude my cognitive understanding. I think I understand 'what' they are, but i haven't connected the dots yet in regards to how you solve problems with them. The are a native feature of ExcaliburJS, now its time to learn!

#gamedev #indiedev #excaliburjs

Great coding session today: lots of good chatting, and several new followers!!

Lots of features worked on, posted in the child post due to character limit

Thanks to all that joined the stream this morning!

Random platformer update.

The Rune/Job system has primary and secondary actions added to it now... so when i create rune content, the will imbue the player with new abilities.

For example: throwing fireballs or having a fireball shield.

#gamedev #indiedev #excaliburjs

platformer update - Collecting Runes!

Got the job system components added plus a collectible rune!

Added a tint shader to player to designate when they have a certain 'power'.... this is fun!!!!

#gamedev #indiedev #excaliburJS

Started experimenting with reusable components to add to Actors, playing with a PickUppable Component to add to an object so when my player collides it gets grabbed.
Next is an 'ImbuesMagic' type component so that when the player hits a rune, they gain some ability...
#gamedev #indiedev #excaliburJS

More platformer practice...

Got my control and animation components added to my player... not the best artwork, but for this kinda of prototyping, it WORKS!!

But that's only the first part! I mocked up a simple level editor in the process!

Hopped back on the behavior tree visualization for a bit tonight, got deleting nodes functional.

Deleting nodes is a bit tougher than adding nodes, especially when managing children.

This is starting to take shape.

I've just refactored my Behavior Tree library that works with ExcaliburJS, I'm now pivoting to developing some tooling to make building the 'content' of an entity's BT, and make this 'easy' to scaffold up with some code generation

Hey BSKY, I've learned a ton from these brilliant folks.... I HIGHLY recommend giving this a listen if you're into TypeScript. Good people!

Two weeks off-track, but progress resumed. Did a bit of excaliburjs today – figured out how to animate smoothly

Had some wins today with different SDF occluders.

Got a spotlight occluder working with a point light on the entity. I did a happy dance when this started working. Also you can see that the room contains the light completely. That's because of my empty box SDF.

#gamedev #indiedev #excaliburjs

Lighting system update

Made some good progress today and learned some more details.

Fixed my bug with rotated occlusion.

Also, learned that I have to update the textures each pass or my occlusion logic doesn’t work.

#gamedev #indiedev #excaliburjs

Made some progress on my lighting system tonight... it needs a lot of optimizations and just... a lot of work in general, but I needed a night like this where stuff kind of just... worked

Solid day today... fixin' to test out my new lighting system for ExcaliburJS... but to rapid prototype it, I'm using SpriteFusion to quickly create a quick floor tilemap....

If you haven't used SpriteFusion yet, give it a try

Hit a milestone today!

I've been working on porting ExcaliburJS to a headless server and today I got the Collision System working server side!!!!

Super stoked.... This may be ready for others to start playing with!
