Weekly Updating 3: Turn, Turn, Turn.

I have an incredibly good excuse to not update this week, but I'm going to go through with an update anyway. It's going to be short.

Last week I got a comment linking me to the KnP tips & tricks thread here on Glorious Trainwrecks. One of the last posts in that thread was about making an object turn towards another object or direction. I remembered asking that very question of the KliK Kommunity a long time ago, and receiving almost the exact same answer: later Clickteam products have the direction calculator, which solves the problem entirely.

Not content with this, I decided to finally solve that problem in KnP. I got out some paper, sketched out the problem, and found a simple solution. I knew there were 4 situations. The first two were obvious: If the target angle is greater than the current angle, add to current angle (and vice versa). The second two were difficult. Under what situation should you subtract to get a larger number, or add to get a smaller number? What was the difference between moving from 12 to 20, and 4 to 28? The difference was, unsurprisingly, the difference. Once the absolute value of the distance between current and target grew greater than half the circle, it made more sense to loop around 0 instead. A bit of figuring, and voila! Turn Towards accomplished in KnP.

Note that this technique alone only works for one object, not a swarm of objects, because direction retrieval doesn't know which object pair to select from and give to. But that's a whole 'nother article. "Object selection" is one of the most confusing aspects of KnP event writing. Sometime I'll talk about that in greater detail. But for now, here is an example of a basic turn towards effect. Enjoy!

Serenade: A Klik & Play Love Poem

I made my wife a Klik & Play Valentine on the bus yesterday. It's like Rod Humble's The Marriage, only the marriage depicted doesn't suck, and there's helicopters. Thought you guys might appreciate it.

intermission!

Fellow trainsurfers, I am moving my ass interstate (Sydney, to be precise) in pursuit of the three pillars of society: beaches, bitches and a philosophy major. So, I will be MIA like olivia newton-john's boyfriend until I get my computer working, an internet connection, and a fixed address, and not necessarily in that order. Needless to say I will miss this month's KotMK. Also, needless to say, I'll be back, with a head full o' ideas and salt water.

Until then!

Keep the spirit alive, etc.

Progress in animation (ZSBK)

I've been beavering away at this for the past few days which explains the week or so between updates.

If cabinets and snapman can impress us with their groundbreaking engine manipulation then I guess I will have to impress through animation.

Beholden to my combo animation concept (which looks funny as she's walking on the spot and there's nothing in the background);

The next thing I will have to do is implement it in a way that positions the player at the coordinates of the final frame of each individual sword swipe so that it won't look like it's instantaneously jumping back to where the animation started. It wouldn't be too bad for the first swipe since the sprite only steps forward a few pixels but for subsequent swipes it's going to look damn amateurish and I'd like to have an air of above-amateurish around this game. Also have to adjust the speed of the animations depending on the frames since there's a bit of that in the gif. Not forgetting fixing inputs so you won't be constantly attacking whilst you hold down the attack key, I'd like some modicum of timing in there.

Holy freaking rhinocerous on a coke binge, batman, we have a KnP ROGUELIKE

...well, more a proof of concept.

But seriously, I present the first version of Krawl! At this stage, it's just a random maze generator. It takes a little while, but it's kinda mesmerising. Linear searching of a matrix has never been so much fun!

This took me some hours. Though I've gotta say, it is one of my proudest achievements in Klik & Play to date.

Next step is making it look like a mad proppa dunjin with rooms and naturalism and all that bebop, but I'm a little spent.

Edit: For those interested, the algorithm is a slightly modified version of part I of this page . That page, in turn, came from the pretty interesting (for the mechanics-minded of you) 300 mechanics page.

Weekly Updating 2: The Best Movement

Welcome to part 2 in our ongoing series of weekly updates on my experiments with my old friend, Klik & Play. Last week I discussed linked/paired object chains, and their potential application to swing simulations. While I considered using this week's entry for a further discussion on pairing or the advantages of wait-based simulation, I decided to talk a bit about one of the most overlooked object movements in KnP: The Platform Movement.

The Platform Movement is generally looked down upon. It doesn't function well with sprite animations of irregular height and hotspot combinations, landing a jump zeros horizontal momentum, its rudimentary inertia simulation mirrors momentum when the player tries to switch directions, and the wall jumping bug is well known. But despite all this, the built-in platform movement has great potential.

If you've every tried to make a two-player game with the platform movement, I'm sure you've noticed that the "bounce" condition when applied between two platform movement objects treats the slower/unmoving player as a wall. But a simple trick can change that dynamic. One of my recent experiments was to try transference of inertia between platform objects of different speeds. It's simple. Three events. The first tests collision, and object A moving faster than B. If A is faster, B takes its direction, and both object swap speed. The second tests collision, and object B moving faster than A. If B is faster, A takes B's direction, and both objects swap speed. The third event simply tests collision, and results in a bounce. The effect of this (with tweaking) is the ability to unexpectedly shove the other player off a platform, or into a trap.

But the greatest potential I found came from not using the platform movement as a player movement. Set a number of these object to control by an imaginary player 2, and lock player 2 input at the start of a level. When two of the same collide (from being shoved by a player object), "switch position with another object" and the two appear to transfer inertia from horizontal collisions! I've found a few other tricks with locked platformer objects, but I'll probably save them for the next KOTM. It's coming up in about 11 days, I think?

Zombie Slash Bikini Killers, the list-ening

I've decided to compile a list of stuff for the next release, for shits and giggles. Feel free to print it off and tape it to the side of your monitor so you can add exclamation marks next to the features that I neglect to add.

- Sexy combo animations
- Zombies that change attacks/animations based on how much of their
shit gets messed up
- Use hitboxes for attacks instead of that separate sword-trail object
- Hidden meaning that compares the relationship of the zombies and
the claustrophobic urban setting as some sort of reference to the
mental struggle of humanity and their modern day environments
- Puddles of gore that hang around due to the low amount of on-
screen dead people (so no huge swarms like in Dethbus and
Zombie Invasion: the Body Explosion).
More blood+less zombies=more violence!
- Trash and chaossss!!!!

Potential Controversy

Two days ago I had an incredible idea for a hilarious, but easy to make game. I've spent some time collecting the basic sources for it, ranging from sounds to art, to ideas, to "implementation/translation". There's just one problem with this idea. It is likely to be highly controversial. It's a parody of a well known game series, but with a strong message, that is likely to upset a fairly large group of people. The presentation is pure Stephen Colbert, where I present ideas in an accurate, but self-contradictory manner.

The game would not be fun, for the most part. Much of the humor would come from this fact. But it would be interesting, and informative.

I sometimes wish Glorious Trainwrecks had private messaging. I'd like to ask SpindleyQ if he feels it's appropriate or not. If I find him on IRC, I'll ask him there. If he thinks it would be too much hassle for Glorious Trainwrecks, or not in the spirit of the site, I'll take the idea in another direction: either as a Shockwave Flash game submitted somewhere else, or as an animation on YouTube.

My first instinct was to make the game in Klik & Play, simply because I've been getting to grips with the system again, and I thought it would be a fun experiment. But the topic may be too serious for the light-hearted nature of our community.

Zombie Slash Bikini Killers

Test release.

Use the arrers to catwalk strut around, Z to give it all some bladed wrist action and C to magically appear more zombies.

In my continued efforts to avoid working on Monster Mashers (and due to a bolt of inspiration) I am now working on what is basically Oneechanbara with a dinky visual style and more exploitive animations. I've laid down the basic groundwork here which I will obviously elaborate on further. Zombies will wander around aimlessly until they approach a 64 pixel radius to you where they will then home in. Slashing them with your sword will cut them in half when they will shortly disappear. Only a maximum of 32 zombies can hang around at once if you ignore the few that are hanging around at the start, slightly more than 32 if you leave those cats be. I intend to enlarge all the sprites but only after I have all the animations done so you'll have to bear with the titchy bird and her dead friends for the time being.

Next version will probably have more attack animations (combos!), blood, zombie dismemberment and my version of the 'tired' animation which is totally different as it involves more ass shaking and breast swaying. Achievement Unlocked: Objectivism Get!
