为什么我的碰撞在 pygame 中不起作用？

Question

This post is part of the Color Meaning Blog Series, detailing the meanings associated with colors such as red, orange, yellow, green, blue, purple, grey, black, white, brown, pink, turquoise, gold, silver, and beige.

Yellow, the color of sunshine, hope, and happiness, has conflicting associations. On one hand yellow stands for freshness, happiness, positivity, clarity, energy, optimism, enlightenment, remembrance, intellect, honor, loyalty, and joy, but on the other, it represents cowardice and deceit. A dull or dingy yellow may represent caution, sickness, and jealousy.

Studies show that the meaning of the color yellow can be warmth, cheerfulness, increased mental activity, increased muscle energy. The color yellow helps activate the memory, encourage communication, enhance vision, build confidence, and stimulate the nervous system.

Answer 1

i am no python programmer but just looking at your collide function

assuming that your colliding base on distance between 2 points on a 2D plane

after getting the distance, you did a (distance mod the sqrt of 2).

a mod get your the remainder of a division, to be exactly 0 means that your number will be a multiple of sqrt2, and since in computer science a floating point 0 is almost impossible to get due to how floating points values is stored.

and after your check whether formula is getting your 0 OR an negative number. since sqrt will never get a negative value from your distance formula for your collide to be true it has to be 0.

suggestion for change, after getting the distance,

Do a check whether it falls within a RANGE with each, if it is true, else false.

google: circle to point collision, my syntax maybe wrong as i am a primarily c programmer,hope it helps
