What Are You Working On Now?

These look much better at the full 65 frames per second.

Looks pretty neat anyway! Looks like a fun element to a level.

It's cool to see what people are doing with Lua, I tend to just get a view of what's happening on development end, which is cool but mostly consists of test cases rather than actual content.

So, I've been working on a cool animation system with rotation, pivots, scaling, parenting etc. it technically works (as in: it draws the sprites at the correct scale and rotation), however, position is kinda messed up, probably because I got something wrong when calculating a sprite's position through its parent's positions. Should be fixable though!

I would urge you to use a transformation matrix for this calculation. It's a much neater system and allows arbitrary transformations (rotation, scale, position, etc.) to be passed down to child objects, regardless of how many parent transforms it's already using, in a very easy-to-manage way (you just multiply the matrices together). It's a very powerful system, and one that most game engines will use.

Vectr will do all the actual matrix maths for you, so all you'd need to do is define the matrices from the transforms you want. How to do that is readily available information on things like Wikipedia: https://en.wikipedia.org/wiki/Transform ... r_graphics

So, the way to go would be...

1) Translate each of the vertices for an image in a way that the pivot point is at the origin
2) Apply scale
3) Apply rotation
4) Translate so the Pivot is now at the specified position

Would it make more sense to turn all of this into 1 matrix or just apply each of these matrices after each other?

Also, as for the position for a sprite with parents, that can't just be done by chaining the transformations, right? Since this involves anchor points on a sprite's parents which are what the sprite is located in relation to.

Absolutely by combining this into one matrix, but to do this all you have to do is multiple the matrices together in the reverse order from the one you want them to be applied.

Absolutely you can! This is the whole point! The position of a child object should be relative to its parent location, so if the position is set as "0,0", it will be on the parent's anchor point. This allows you to apply the parent transformation, which puts it on the parent's pivot, followed by the child transformation, which offsets it from that pivot. This is hugely powerful, as this also applies to scale and rotation if you set it up right, so rotating a parent would rotate all of the children too, and the child's rotation would be essentially added to the parent rotation.

One note though - you likely want to apply scale and rotation BEFORE you apply translation. These two transformations are most easily done with respect to the world origin, so applying them before applying the position means they will be correct to the object's pivot point.

Got animation to work! It looks great imo.

I blame pyro for this one. Any guesses as to who it is? (WIP)

Sonic the Hedgehog maybe? I know Pyro wanted a playable Sonic in SMBX 2.0 & Toad is the fastest character after all. In your gif, Toad also seemed to charge up something, which I presume to be a spindash. That's my best guess anyway...

I think "Ground Pound" is a better name for it

This one is a bit more advanced. I think it's possible to find out who it is if you know the character.

Sometimes I press down while jumping to better avoid projectiles. Wouldn't it be better to have the player hold another key while pressing down to execute the ground pound?

Good point, I'll probably change it to the tanooki button.

When are you releasing that?

[PixelPest]

I'm working on updating my galaxyComets API. It will involve more comet missions and features, as well as a new HUD with the SMG life counter. Read more about it here: http://www.smbxgame.com/forums/v ... 63#p223263. Screenshots coming soon to a Screenshot Thread near you

[MECHDRAGON777]

A Way to have battle stages have a profile setting. (For when Online play comes into effect.) ...it would be more of a level and lua code, and not an API, but still. I think it would be helpful.

Edit, also, I am making a Contest level with some lua, but I o not know if that is "advanced or basic" coding.

[Rixitic]

Back to lua after a bit of a slump, finally finished up proportional fonts, tailed word bubbles and NPC tracking in textblox.

Spoiler: show

Currently auto-tracking and positioning only works through lua-generated Text Blocks, but I'm gonna see if I can get the library to keep track of which NPC initiates a message so it'll work with npcParse and/or overridden vanilla messages.

[PixelPest]

Just finishing off smgModder.lua (my Super Mario Galaxy "Mod.") at the moment. I'll release a few more updates to it after some bugs or opportunities to optimize the code are found, or any new ideas to implement are discovered.

after that, I plan to remake the Peach/Toad/Link HUD to be usable by Mario and Mario/Luigi's HUD to be usable by Peach, Toad, and Link, including item boxes
