禁用某些物理物體的重力

Question

如何使用LOVE物理物件禁用某些物理物體的重力？

blocks.ground.body = love.physics.newBody(world, 0, blocks.ground.y, "dynamic") 
blocks.ground.shape = love.physics.newRectangleShape(500, 50) 
blocks.ground.fixture = love.physics.newFixture(blocks.ground.body, blocks.ground.shape) 
blocks.ground.color = {86,176,0} 

這是我的身體當前的代碼，我也需要它保持「動態」，因爲我需要移動的X

Answer 1

假設你是使用LÖVE0.8.0+：

選項1：

代碼：

blocks.ground.body = love.physics.newBody(world, 0, blocks.ground.y, "dynamic") 
blocks.ground.shape = love.physics.newRectangleShape(500, 50) 
blocks.ground.fixture = love.physics.newFixture(blocks.ground.body, blocks.ground.shape) 
blocks.ground.color = {86,176,0} 

注：在你的代碼love.physics.newFixture(blocks.ground.body, blocks.ground.shape)

從戀愛的網站（1）：

objects.ground.fixture = love.physics.newFixture(objects.ground.body, objects.ground.shape) --attach shape to body 

從戀愛的網站還（2 ）：

objects.ball.fixture = love.physics.newFixture(objects.ball.body, objects.ball.shape, 1) -- Attach fixture to body and give it a density of 1. 

在從他們的網站的第二代碼段，他們設置球密度（質量）至1。同樣，您應該能夠將質量設置爲0，在這種情況下，重力對物體沒有影響。但是，如果其他對象與您的對象碰撞，質量0，我不知道什麼類型的時髦行爲可能會發生。

選項2：

另一種選擇是創建一個新的世界的0比重：

love.physics.setMeter(64) --the height of a meter our worlds will be 64px 
    worldNoGravity = love.physics.newWorld(0, 0, true) 

然後屍體添加到世界：

blocks.ground.body = love.physics.newBody(worldNoGravity , 0, blocks.ground.y, "dynamic") 
blocks.ground.shape = love.physics.newRectangleShape(500, 50) 
blocks.ground.fixture = love.physics.newFixture(blocks.ground.body, blocks.ground.shape) 
blocks.ground.color = {86,176,0} 

希望其中之一將爲你工作:)。
