我怎样才能改善这个跳跃? [英] How Can I Improve This Jump?
问题描述
您必须多次显示相同的动画图像.例如当 jumpCountStart = 20 时，您必须将每个图像显示 2 次.当 jumpCountStart = 50 时，您必须将每个图像显示 5 次.
self.jump = [pygame.image.load("grey_mouse/jump (" + str(i) + ").png")对于 i 在范围 (1, 9)]重复 = jumpCountStart//10self.jump = [self.jump[i//重复] for i in range(len(self.jump) * repeat)]VIDEO < this is my problem my jump is jumping way to fast and I dont event have time to move beaten where I Jumped from Is there a way I can improve this jump without slowing down my sprite fps? if I tried to slow down my sprite fps that would cause my sprite to play its animation way to many times when I jump. I am trying to make this jump smooth as possibale but right now its jumping way to fast and also the animation plays to fast

The jump time depends on the constant 10 used in the jump algorithm. Use a jumpCountStart variable instead of this constant.
jumpCountStart = 50
The height of the jump also depends on this constant. Scale the jump with 10 / jumpCountStart so that the height of the jump does not change when the jump is slowed down:
while run:
# [...]
if not playerman.isJump:
# [...]
pass
else:
if playerman.JumpCount >= -jumpCountStart:
jumpHeight = playerman.JumpCount * 10 / jumpCountStart
playerman.y -= (jumpHeight * abs(jumpHeight)) * 0.4 * 10 / jumpCountStart
playerman.JumpCount -= 1
else:
playerman.JumpCount = jumpCountStart
playerman.isJump = False
# [...]
Don't forget to initialize the attribute JumpCount with jumpCountStart:
class player:
def __init__(self,x,y,height,width,color):
# [...]
self.JumpCount = jumpCountStart
Animation with jumpCountStart = 50:
You have to show the same animation image multiple times. e.g. When jumpCountStart = 20 you have to show each image 2 times. When jumpCountStart = 50 you have to show each image 5 times.
self.jump = [pygame.image.load("grey_mouse/jump (" + str(i) + ").png")
for i in range(1, 9)]
repeat = jumpCountStart // 10
self.jump = [self.jump[i // repeat] for i in range(len(self.jump) * repeat)]
