Lua color code generator9/5/2023 ![]() ![]() In my opinion, this is the coolest type of LED strips. So, they can be left outside at the rain and dust without any problem. It is 5 meters long and the LEDs are enclosed in a weatherproof silicone. In the following figure you can see my WS2812B LED strip. You can visit Maker Advisor and find the WS2812B RGB LED Strip best price. Choose the one that best fits your purposes. The WS2812B addressable LED strip comes in several models that differ in size, sealant or LED density. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others. The rectangle the sprite occupied when the touch happened.This post is about the WS2812B LED strip, which is an addressable RGB LED strip. The coordinates where the sprite started touching other. Use this value to determine things like if your character is touching the ground. ![]() The collision normal usually -1, 0, or 1 in x and y. The difference between the original coordinates and the actual ones when the collision happened. ti: A number between 0 and 1 indicating how far along the movement to the goal the collision occurred. False if it didn’t overlap but tunneled through other. ![]() True if the sprite was overlapping other when the collision started. other: The sprite colliding with the sprite being moved. Each item in the array contains values for the following indices: If no collisions occurred, this will be the same as goalX, goalY.Īn array of userdata objects containing information about all collisions that occurred. Returns actualX, actualY, collisions, length. XPhase, yPhase: optional integer values that affect the appearance of, ,, , 2x2, 4x4, and 8x8. PadEdges: Boolean indicating whether the edges of the images should be padded to accommodate the blur radius. (We aren't using timers in this example, but in most - average-complexity games, you will.) if playdate.buttonIsPressed( playdate.kButtonUp ) thenĮnd if playdate.buttonIsPressed( playdate.kButtonRight ) thenĮnd if playdate.buttonIsPressed( playdate.kButtonDown ) thenĮnd if playdate.buttonIsPressed( playdate.kButtonLeft ) thenĮnd - Call the functions below in playdate.update() to draw sprites and keep - timers updated. (There are multiple ways to read the d-pad this is the simplest.) - Note that it is possible for more than one of these directions - to be pressed at once, if the user is pressing diagonally. Poll the d-pad and move our player accordingly. Use this function to poll input, run game logic, and move sprites. This function is called right before every frame is drawn onscreen. `playdate.update()` is the heart of every Playdate game. After this runs (it just runs once), nearly everything will be - controlled by the OS calling `playdate.update()` 30 times a second. x,y,width,height is the updated area in sprite-local coordinates - The clip rect is already set to this area, so we don't need to set it ourselvesĮnd - Now we'll call the function above to configure our game. local backgroundImage = ( " Images/background " ) (This is what we're doing below.) - 2) Use a tilemap, assign it to a sprite with sprite:setTilemap(tilemap), - and call :setZIndex() with some low number so the background stays behind - your other sprites. There are generally two ways to do this: - 1) Use setBackgroundDrawingCallback() to draw a background image. PlayerSprite:add() - This is critical! - We want an environment displayed behind our sprite. PlayerSprite:moveTo( 200, 120 ) - this is where the center of the sprite is placed (200,120) is the center of the Playdate screen local playerImage = ( " Images/playerImage ")Īssert( playerImage ) - make sure the image was where we thought The :moveTo() call moves our sprite to the center of the display. The :setCenter() call specifies that the sprite will be anchored at its center. local playerSprite = nil - A function to set up our game environment. We'll scope it to this file because - several functions need to access it. NOTE: Because it's local, you'll have to do it in every. Instead of having - to preface all graphics calls with "aphics", just use "gfx." - Performance will be slightly enhanced, too. Import " CoreLibs/timer " - Declaring this "gfx" shorthand will make your life easier. You'll want to import these in just about every project you'll work on. Your game can use multiple source files if you wish - (use the `import "myFilename"` command), but the simplest games can be written - with just `a`.
