Tappy Lander Dev Diary #6: Scoring, Risk & Reward

I love going for a high score! I first tried back in the arcade days and again when home consoles were in their infancy, but as they grew, the tech grew, and soon visual storytelling trumped scores and they nearly disappeared.

Then games grew even further. The market expanded, the internet came, and Microsoft tried something crazy with achievements and gamerscore, little indies threw out the rules out and started making games about everything, and arcade experiences made a comeback on our telephones of all places!

So scoring is back, thank goodness. Both Apple and Android platforms are great places to challenge your friends, again.

That pesky buggy!
Scoring

Tappy Lander is all about scoring. A successful landing on a each pad nets you points (based on the precision of your landing) and, if you’re feeling dangerous, you can grab a data disk for 1000, pop a buggy for 1000 or rescue tomatoes for 1000, apples for 2000, bananas for 4000 and the ultra rare carrot for 8000!

Disks, buggies, fruit and veggies are rare and may not appear at all. If they do appear, they are in hard to reach areas or places where going for them may put you in danger, so don’t get too greedy!

Oh, who am I kiddin’? Get greedy! Get reeaal greedy! Beating your friends will not be easy because of the risk reward system.

Risk & Reward

If you successfully land your rocket you will be given two choices. You can either “Cash In” to cash in your points to level up and submit your high score to the game network or you can “Risk It” and go on another random run, adding to your current score but risking losing everything. Tappy Lander is a game of permadeath. If you blow up, you lose everything, no matter how big your score is. Getting to the next landing pad is ALL that matters.

Leaderboards

There are four leaderboards:

  • Biggest Bounce (See dev diary #5)
  • Longest Slide (See dev diary #5)
  • Best Run (Best score in a single run including pickups, pops, tricks and accuracy)
  • High Score (The mother of all leaderboards)

The Big Picture, Your High Score!

At the end of your run, danger points are tallied for your pickups and buggy pops along with points for bounce, slide and accuracy. Once added together, a risk percentage is thrown in to boot! The more you “Risk It” the higher your risk percentage gets which can make or break your placement on the High Score leaderboard!

Next I will discuss achievements and the data disk collectables.

Tappy Lander Dev Diary #5: Physics & Tricks

You’ve practiced and taken all variables into account. You zero in on the target. Finally, through the combination of calculation, instinct and luck… SWISH! Two points!

I believe the popularity of physics in games is due to two things.

  • Familiarity Physics gameplay allows you to use the instincts you have developed since childhood. You’re using real-world skills to do the impossible in a virtual environment.
  • It Feels Good It gives you a sense of accomplishment that you only get in physics simulations. The same feeling you get when you successfully shoot a basketball.

Tappy Physics

Being created with Corona SDK and Box 2D, an open source physics engine, Tappy Lander is a game that pits your piloting skills against your biggest enemy, gravity. The physics engine handles the forces of your thrust in a semi-weightless environment splendidly. It also handles collisions so that your ship explodes only when it feels like it should, and the falling debris bounces around on the ground realistically. Although some of the collision code is built from scratch, most of it relies on the Box 2D engine. Friction, bouncy-ness and gravity of each planet varies and is all controlled by Box 2D.

Emergent Gameplay

One of the joys of physics is that you get all kinds of fun and sometimes unexpected results. The first time I landed in the prototype I noticed a little bounce. At first I thought “Wow, that looked realistic and cool”. My imagination sparked, I quickly then asked. “What if you get extra points for a higher bounce”?

Tricks

Both the slide and the bounce trick (seen here in the Tappy Lander Trailer) was made possible and inspired by side effects of the physics code. Some planets have less friction than others, allowing a super long slide if you come in at the right angle with enough thrust. Other planets are softer and bouncier, allowing for a super high bounce. Tricks yield lots of points when done correctly but are very risky and easy to botch.

  • Sliding A proper slide requires that you touchdown onto the landing pad and slide off of it into the planet terrain. If you touchdown on the planet terrain at any speed your rocket explodes. Oftentimes when attempting a slide you will either overshoot the target or skip off the target and hit the ground.
  • Bouncing If gravity is low and you come across a soft planet, conditions are perfect for a high bounce. Remember, however, one of the fundamental rules of landing: hitting the target too hard results in an explosion-so be careful! A 2000 point bounce unlocks the “Megabounce!” achievement and its possible to get an even bigger “Gigabounce!”

That’s how physics work in Tappy Lander and now you know the origin of the trick system! Next… I’m not sure what I’ll talk about yet!
