How to deal with slopes in platformer physics?
Tile number two is empty, so we need to check the tile below it and see if the offset from the character to tile number 3 is proper to keep walking along the slope there. It’s going to be easier to handle these corner cases in the horizontal collision checks, so let’s head back to the CollidesWithTileRight function.
How do you make a slope stick in platformer?
First off, to handle the slope sticking, the mSticksToSlope flag needs to be set, the object must have been on the ground the previous frame, and the move flag needs to be on. Now we need to find the tile to which we should stick.
How big of a file do you need for slopes?
Right now, if the tile size in our game was bigger, say 32×32, each tile type would occupy 8 MB, and if we used 64×64, then it would be 128MB. These amounts seem way too big to be useful, especially if we want to have quite a few slope types in the game.
How many bytes of data do you need for slopes groundwork?
Since the tiles we are using are 16×16, this means that the amount of data needed for each tile type will be 16*16*16*16*8 bytes, which equals 512 kB.
How do you do slopes in Minecraft demo?
The demo shows the end result of the slope implementation. Use WASD to move the character. Right mouse button creates a tile. You can use the scroll wheel or the arrow keys to select a tile you want to place. The sliders change the size of the player’s character.
How is movement split in a 2D platformer?
If a movement for a particular frame is larger than one pixel, then the movement vector is split into many 1px movements, and after each one the conditions for collision with the terrain are checked. This saves us the headache of trying to find obstacles along the line of movement at once, and instead, we can do it iteratively.
What do you need to know about slopes?
Let’s start defining the data that we’ll need to represent the slopes. First of all, we’ll need a height map of a slope, which will define its shape. Let’s start with a classic 45-degree slope. Let’s also define another slope shape; this one will serve as more of a bump on the ground than anything else.
