Construct 3

Layout - A level in construct is called a layout. Each layout can have it own properties and event sheet

Event sheet - allows for basic programming of a level. This is used when behaviour do not work. 

Properties - variable (or values) that can be changed for a layout or a sprite such as movement speed or camera size. 

Sprite- A object in construct. Object can be given behaviours to change how they interact with elements of the game. 

Behaviour - changes how objects interact with each other, the player and the world. For example the solid behaviour given to an object is impassable by the player.
