Obstacles & map features

All adventure maps, cup and and event tracks things that affect gameplay consist of two things: **ground** and **obstacles and other features**.

Basically ground makes the basis for map and obstacles are all the other things. Every adventure map has at least one ground type whose texture is different from other maps. Sometimes the map has more than just one ground texture like Racer Glacier has three differents. It's also sometimes hard to make the split between ground and obstacles, e. g. it's hard to say is Overspill Fun Rig's roller coaster platform ground type or obstacle(I think it's not). Most of the ground types work in a same way but there's one exception: snowy or icy ground. These ground types are found in four maps: Mountain, Winter, Racer Glacier and Raging winter and the und to other ground types is their slipperiness. All vehicles have less grip on these surfaces but it can be helped with winter tires, they increase grip on snowy surfaces. It's also possible that all other ground types slipperiness is a bit to others and every ground type is unique by also that way. Technically a map can be built by only ground and many Hill Climb Racing 1 maps have been made of only ground as well but then the map will be very unilateral and boring.

Here's list of all ground types in the game:

* Normal surfaces:
	+ Countryside.
	+ Forest.
	+ City.
	+ Mountain normal
	+ Rustbucket Reef sand (normal)
	+ Rustbucket Reef coral (ceiling)
	+ Mines
	+ Desert valley
	+ Desert valley rock (ceiling)
	+ Beach
	+ Backwater bog
	+ Racer glacier cave
	+ Patchwork plant
	+ Gloomvale dark green (normal)
	+ Gloomvale light green (higher areas and ceiling)
	+ Overspill fun rig green (outside)
	+ Overspill fun rig brown (haunted house)
	+ Canyon arena
	+ Sky rock outpost
	+ Race track
	+ Halloween event
	+ Chinese new year event
* Snowy surfaces:
	+ Mountain snow
	+ Winter
	+ Racer glacier outside
	+ Racer glacier ceiling

Obstacles are much more various than ground types and there's even some things of that I'm not sure are they called obstacles so I will call them special features. Obstacles also, unlike ground types can be found from many different maps. Many obstacles also resembles each other so they have been divided to groups like logs or liquids. Obstacles can be divided to breakable and unbreakable obstacles. Breakable obstacles durability also varies. You can also divide obstacles to those that can't cause driver down and to those that cause (most obstacles).

Here's list of all special features in the game:

* Gravity
	+ Earth gravity
	+ Moon gravity
* Wind
	+ Many different strengths and directions of wind

Here's list of all obstacles in the game:(+ = breakable obstacle)

* Logs
	+ Short thick hanging log held by one rope in the middle
	+ Longer thin (length varies) hanging log held by two ropes in both ends
	+ Short thick swinging log held by one rope in the middle
	+ Short thick hanging log held by one rope in the middle, similar log above in the same rope
	+ Short thick swinging log held by one rope in the middle, similar log above in the same rope
	+ Stack of six long thin logs on the ground (height three logs, three logs behind others)
	+ Small logs in a row on ground, can't be moved
	+ Small logs floating in a row in water
	+ Stack of three ends of logs on ground in vertical position, first log shortest third tallest like stairs
	+ Small log on ground, can be moved
	+ Big thick weak log +
	+ Thin different heights logs used to make platforms where to drive, jumpers or supports for these
	+ Long thin swinging log held by two ropes in both ends, fixation points above on the rock in different places
	+ Long thin swinging log held by two ropes in both ends, fixation points above on the rock in same place
	+ Long thin swinging log held by one rope in middle, fixation point above on the rock
