python - Pygame Making A Sprite Face The Mouse -

-

im new pygame kinda ok on python, im creating zombie shooting game overhead view.
managed make character move when pressing arrow keys. need player face mouse/cursor without clicking screen time.
help?

for event in pygame.event.get():     if event.type == mousemotion:         mousex, mousey = event.pos         # build vector between player position , mouse position         movevector = (mousex-playerx, mousey-playery)          """         compute angle of movevector current vector player facing (facevector).         should keeping , updating unit vector, each mouse motion         assume have initial facing vector (1,0) - facing east         """          # compute angle in [1]          # rotate image angle , update facevector

[1] - how find angle between 2 vectors: http://www.euclideanspace.com/maths/algebra/vectors/anglebetween/index.htm

your image may lose quality when rotated @ small angle. it's discussed in pygame documentation page: http://pygame.org/docs/ref/transform.html#pygame.transform.rotate

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
