[英]AssertionError: The shape's body must be added to the space before (or at the same time) as the shape
我正在嘗試制作一個游戲,其中包含 pymunk 中的多邊形,為了能夠在 pymunk 中做到這一點,我決定使用許多段並將其繪制為實心多邊形。 當我執行代碼時出現錯誤
我的代碼
class StaticPoly:
def __init__(self, space, pos, elasticity=1, collision_type=None):
self.bodies = []
self.shapes = []
self.pos = pos
for i in list(range(0, len(self.pos) - 1))+[-1]:
print(i)
self.bodies.append(pymunk.Body(body_type=pymunk.Body.STATIC))
self.shapes.append(pymunk.Segment(self.bodies[i], self.pos[i], self.pos[i + 1], 1))
self.shapes[i].elasticity = elasticity
space.add(self.shapes[i])
if collision_type:
self.shapes[i].collision_type = collision_type
錯誤:

StaticPoly.bodies
包含pymunk.Body
s。 這些實體也必須添加到空間中。
Reed 錯誤信息:
形狀的主體必須在添加到形狀之前(或同時)添加到空間中。
無論是之前
space.add(self.bodies[i])
space.add(self.shapes[i])
或同時
space.add(self.bodies[i], self.shapes[i])
