计算龟与斑块之间的角度

Question

如何计算图中指定的上述角度。 贴片事先已知。

Answer 1

我不会为它编写代码，但这是一个通用的配方：

• 通过在pxcor和pycor添加/减去0.5来查找补丁的四个角点;
• 使用distancexy;
找到最近的两个角
• 使用towardsxy;
查找这两个点的标题
• 使用subtract-headings
计算这两个标题之间的差异

Answer 2

  let px [pxcor] of patch-goal
  let py [pycor] of patch-goal
 ; show  [pxcor] of patch-goal
  set corner-1 list (px + 0.5 - .25)(py - 0.5)
  set corner-2 list (px - 0.5 + .25)(py - 0.5)
; show corner-1 
; show corner-2
  let head-1 towardsxy (item 0 corner-1) (item 1 corner-1)
  let head-2 towardsxy (item 0 corner-2) (item 1 corner-2)
  report abs (subtract-headings head-1 head-2)  
end
