LevelView

Class representing view of level displayed of screen.

Properties

• messages_font - font used to display win and loss messages on screen.
• frames_per_simulation_tick - number of frames displayed between each two ticks of level simulation.
• frames_till_next_tick - used as iterator to count number of frames to display before next tick of level simulation.
• level - engine.level.Level type object which components are displayed on screen.
• simulation - gameplay.simulation.Simulation type object that level simulation is managed by.
• main_frame - pygame.Surface type object, on wchich level should be displayed.
• board_frame - main_frame subsurface, on which level board should be displayed.
• controls_frame - main_frame subsurface, on wchich buttons controlling level simulation should be displayed.
• buttons - list of gameplay.button.Button type objects, that are buttons displayed on controls_frame, which are used to control level simulation.

LevelView(screen, level, frames_per_simulation_tick).

Set main_frame value to screen. Divides main_frame to parts described in level visualisation documentation and saves them in board_frame and controls_frame. Creates predefined buttons to be displayed on controls_frame. Sets level value to level argument value. Sets simulation value to new simulation with level given as an argument in constructor. Sets frames_per_simulation_tick value to value of argument with the same name and frames_till_next_tick to the same value.

refresh()

Refreshes level display. Requested when application displays next frame. Decrements frames_till_next_tick value. If it drops to zero, then resets it to initial value and from now on displays next level simulation tick.

handle_click()

Informs all buttons displayed that mouse button was clicked.

reset_simulation_ticks()

Resets frames_till_next_tick to its initial value. Should be used when restarting simulation, to avoid first simulation tick to be displayed for shorter time than other ticks.
