![]() ![]() A modal screen prevents the userįrom interacting with displayables below it, exceptįor the default keymap. It takes the following properties: modal If True, the screen is modal. It takes one parameter, the name of the screen. The screen statement is a Ren'Py script language statement that is GeneratorsĬan be used in Python functions called from a screen, but not in the Python source code that will be used in a screen context. This traces back to an issue with the way the Python interpreter compiles Using Python generators in screens may cause unpredictable results. Running a screen has side effects, those side effects may occur at Prediction process, before the screen is first shown. Ren'Py will run a screen multiple times, as Screens must not cause side effects that are visible from Up in the scope, and then looked up as a global variable. When a variable is accessed by a screen, it's first looked Note that a with None statement does notĬause an interaction to happen, and hence won't update a screen.Ī screen has a scope associated with it, giving values to some Screens are updated at the start of each interaction, and each time an User to advance the game, control preferences, load and save games,Īnd invoke many other actions. Ren'Py includes a pool of pre-defined actions, allowing the Buttons and bars allow the user to invoke actions and adjust The other thing a screen can do is to allow the user to interact with ![]() To the user, including the character's name and what she is saying. The say screen, for example, is used to display dialogue Some of the information displayed in this manner is vital to Information can be displayed using text, bars, and More than one screen can be shown at a time. Explicitly, using statements that cause screens to be shown.On-screen button that shows the save screen. By default, the save screen is shown when the user As an action, associated with a button, mouse button, or keyboard.Screen when it starts running, or when the user returns to the For example, Ren'Py will display the main_menu The say statement will cause the say screen to be displayed. Implicitly, when script statements execute.The user interface, which is customized using screens. The user using the scene, show, and hide statements, and are generally This is probably your best bet as it will save you processing speed without killing your memory.The things that a user sees when looking at a Ren'Py game can beĭivided into images and user interface. Instead it is recommended that you only run these functions every few steps in an alarm (for example), or if the view has changed position, and it is especially important that you do not use these functions in the draw event as this can lead to serious errors in your game." This will deactivate all the trail objects in the room and activate the ones in the view, with a little buffer on the sides.Ī note of warning from the GM manual: "It is normally not necessary to deactivate instances every step of your game and this can actually cause your game to lag and runs slow. Instance_activate_region(view_xview - 64, view_yview - 64, view_wview + 64, view_hview + 64, false) You could have each trail be an instance and deactivate them when they are out of view, this will cause them not to take up processing time while they can still be reactivated in the game. Basically you have to choose whether to sacrifice memory or speed, whether you have a surface drawn over the whole level or you make lots of draw calls. Where the x values are stored in the 0 position in the grid and y is stored in 1.īut all those draw calls will quickly get out of hand in terms of speed. I recommend storing the trail locations in a ds_grid then in the draw event of your trail drawing object you can have: for(i = 0 i < ds_grid_width(trailGrid) i+=1)ĭraw_sprite(trailSprite, subimage, ds_grid_get(trailGrid, i, 0), ds_grid_get(trailGrid, i, 1)) One way that could work is having a single object draw the sprite repeatedly in the correct locations. You might not have any problem just having each trail piece as an individual object, but objects are pretty heavy weight and can slow your game down if you have too many. Having a surface that draws over your entire level probably wouldn't be a good idea in terms of memory usage, but a background that does the same thing would not be any better, in fact it would be worse. ![]()
