Gravity

Implementing jumping

To implement a jump mechanic, you can follow these steps:

1. Define Variables:
   • Create variables for the player's velocity, gravity, and whether the player is on the ground.

   float velocityY = 0;
   final float gravity = -0.5f;
   boolean onGround = true;
   

2. Jump Logic:
   • Implement the jump by applying an upward velocity when the jump key is pressed and the player is on the ground.

   if (Gdx.input.isKeyPressed(Input.Keys.SPACE) && onGround) {
       velocityY = 10;  // Jump strength
       onGround = false;
   }
   

3. Apply Gravity:
   • Continuously apply gravity to the player's vertical velocity.

   velocityY += gravity;
   

4. Update Player Position:
   • Update the player's Y position using the current velocity.

   player.y += velocityY;
   

5. Ground Detection:
   • Check if the player has landed back on the ground to reset the jump.

   if (player.y <= groundLevel) {
       player.y = groundLevel;
       velocityY = 0;
       onGround = true;
   }
   

By following these steps, you create a basic jumping mechanic where the player can jump when on the ground, and gravity pulls them back down. This can be expanded with more complex mechanics like double jumps or variable jump heights.

Common

Speedy Blupi (Epsitec): In 1998 the Epsitec company released the game Speedy Blupi (Epsitec) for the Windows platform.

• In 2001 Epsitec released Speedy Blupi II, the sequel.

Speedy Blupi (Dada Games): In 2013 Daniel Roux, employee of the Epsitec company, released Speedy Blupi (Dada Games) for the Windows Phone platform. It was released as a product of a Dada Games game studio.

Description

The game, firstly developed by Epsitec for Windows PCs, later developed by Daniel Roux and Dada Game for Windows Phone device, centers around a main hub. The protagonist, Blupi—also called Eggbert—embarks on challenging treasure-hunting quests across several uniquely themed worlds connected to this central hub.

The game features richly detailed backgrounds and thematic elements, including:

• Nature-inspired settings: Trees, grass, bushes, spiderwebs.
• Fantasy and playful worlds: Kid-themed areas, small houses, castle facades, and playground-inspired elements.

Lives

Blupi collects eggs (lives), he can have a maximum of 10 eggs (lives in stock).

Backgrounds

trees, grass, bushes, houses, columns, spider webs, children's world

The marine plant remains purely a background decoration, even though it's included in the object sprite sheet. It doesn’t interact with any objects or elements but will overwrite other decorations if placed on the same tile. As far as I know, it's the only animated decoration in the game.

Blocks

Blocks have different themes.

Transparent or partially permeable blocks.

Some blocks are impermeable but as an obstacle only partially, for example the first quarter of the block is an obstacle or a triangle on the right.

Block motifs: mechanical, rocky, slimy (green), cheese, technical, pipes, grass with earth, palace, house facade, bricks, library, wooden wall, children's world

• Hidden block: (invisible, but impermeable)
• Water block: Blupi can swim but must surface to avoid drowning.
• Lava block: Lava instantly takes one life.
• Fan: blows Blupi in a specific direction (vertically or horizontally)
• Moving blocks that slide between fixed points at varying speeds.
• Moving belt in one direction: a special block
• Special disappearing and reappearing blocks
• Breakable crates.

Key Gameplay Mechanics

• Blupi can pick up a bomb and detonate it in another place - usually for detonating crates (a special type of block).
• If Blupi do not escape in time after detonating the bomb, then the bomb explosion will take one life from them.
• Blupi can move crates
• Blupi can collect red, green or blue keys, after obtaining them, doors of the given color will open for them, if such door is reached.
• Yellow doors will open for Blupi after obtaining a given number of chests (the number of needed chests is on the door sign).
• Teleports: transfer Blupi from one place to another. Teleports are named after the beginning of the Greek alphabet (4 types of teleports)
• Blupi can use tubes in the air - Blupi can move over dangerous surfaces such as lava or mines and others
• After falling on a spring Blupi jumps higher
• A special blue block disappears for a moment and reappears.
• Collapsible bridges crumble after a delay, rebuilding after a short time.

Types of transport: hovercraft, helicopter (engine with propeller), skateboard, car, tank

• These destroy mines: skateboard, car, tank,
• Hovercraft: A fast, floating vehicle that can move over water, lava, or quicksand but is vulnerable to projectiles.

Elements

Lollipop: can be taken by Blupi, then Blupi jumps more for a while.

Invisibility potion: Blupi can collect shields or drink a drink that makes him immortal and invisible for a while for enemies and homing bombs.

• In SB1 it's only for multiplayer. In SB2 it affects also homing bombs (single player)

Game goal

There is a central hub, which points to world hubs. Each world hub points to several worlds (levels).

Treasure Collection: Blupi collects treasure chests in each level to unlock new areas and progress.

Blupi can collect green slime balls (maximum ten) and then throw them from tank or helicopter from a distance at enemies.

Multiplayer

Blupi can play with up to 3 other blupi in multiplayer.

This is only supported in the Epsitec version of the game.

Enemies and hazards

• Unmoving mines (upper, lower)
• Moving minions, which activate and start moving when a blupi approaches them
• Lava: blupi takes one life
• Slime trap: takes one life from a blupi
• Circular machine: takes one life from a Blupi.
  • If you go through them in a hovercraft, jeep or glue tank, you won’t die, but you still will if you use a helicopter or skateboard.
• Circular machine switch: An interactive element, which activates or deactivates Circular machine
• There is an element that causes a blupi to walk in the opposite direction for a while
• Lightning: takes a blupi's life, but the lightning only flashes for a moment, then it is still for a moment
• Squashing device: makes a blupi fall from above for a moment, then the blupi flies down slower and has a different gravity
• Other enemies that cause life loss are a digger, a shark, a bird, a living slime, a mine ball, and flying or riding blue blupi
• Wasp: does not take a Blupi's life, it inflates Blupi, Blupi then float temporarily. Blupi swells up after being stung by a wasp, but deflates after a certain time or when it hits a mine on the top.
