Colobot

Life on earth is threatened by a devastating cataclysm, forcing mankind to move out and search for a new home. A first expedition composed solely of robots was sent to find another habitable planet. However, for unknown reasons, the mission was a disaster and never returned.

With only a few robots for companions, the player must travel to new planets. Houston, Earth Mission Control as well as a spy satellite will transmit valuable information to the player. The player needs to build the infrastructure necessary to gather raw materials, energy supplies, and produce the weapons necessary to defend themselves. By programming robots, the player can delegate tasks to them, allowing the player to continue their mission while their robots upkeep the base, fight off enemies, harvest materials, and perform any other tasks assigned to them.

Bot in colobot

The programming language used in Colobot is CBOT, syntactically similar to C++ and Java. Example code for a bot to find a piece of titanium ore and deliver it to a purification facility:

extern void object::FetchTitanium()
{
	object item; // declare variable
		
	item = radar(TitaniumOre); // find a piece of titanium ore
	goto(item.position); // go to the ore
	grab(); // pick up whatever is in front of the robot (presumably the ore)
	
	item = radar(Converter); // find the ore converter
	goto(item.position); // relocate to the converter
	drop(); // drop the piece of ore
	move(-2.5); // back up 2.5 meters to allow the converter to start processing the ore
}

Epsitec released the games' source code in October 2014 under GNU GPL v3 after being contacted by the Polish game enthusiast community PPC.[1]

ICC & TerranovaTeam (formerly PPC[2]) was given the source code by Epsitec under the GPLv3 license.[1] Terranova is in the process of updating the game, titled Colobot: Gold Edition. They are also working on a sequel: Colobot 2, aiming for a Steam release; however, this goal has not been accomplished yet.

CeeBot, also made by Epsitec, is a very similar series of games spanning 4 titles.

• CeeBot-A - An expansion of Colobot's Exercises & Challenges.
• CeeBot-Teen - Geared to and simplified for a younger audience. Has basic programming exercises.
• CeeBot3 - A program-to-paint programming course that allows students to make drawings & animations
• CeeBot4 - A major programming course for college students & audiences in the programming field.

The game has been recommended by the Polish Ministry of National Education as a teaching aid for learning the basics of algorithms and object-oriented programming.[3]
