walking animation

[kousha41564]

alright watsup guys. i am making a game for fun , and right now i am just working on the walking animations and the colisions. this is a pokemon red blue style thing. you know where you have the bird view thing going on ?

so here is my code, i made a dude, and made his shoes in relation to the position of the dude (cirlce) , now i wud like the feet to move as if he is walking. cant figure it out thogh. any help is apreciated.

code:

View.Set ("graphics:800,600,offscreenonly") var x1,y1,x2,y2,a,b,xx1,yy1, yy2, xx2:int:=0 var sd2,sd1,sdd1,sdd2 : int :=0 %shoe dircection var c,csq:real:=0 var key : array char of boolean x1:=300 y1:=300 x2:=150 y2:=150 sd1 :=15 sd2 :=15 % shoe irection sdd1 :=10  sdd2 := 10 loop drawoval(x1,y1,22,22,7) drawoval(x2,y2,50,50,1) a:=x2-x1 b:=y2-y1 csq:=a*a+b*b c:=sqrt(csq) if 50+22>c then put "collide" end if Input.KeyDown (key) if key (KEY_UP_ARROW) and y1 < maxy then %makes sure the character won't go past the top of the screen xx1 := x1 +10 yy1 := y1 +23 xx2 := x1 -10 yy2 := y1 +23 y1 +=1 sd1 :=10 sd2 :=10 % all sd's change direction of shoes sdd1 :=15  sdd2 := 15 end if if key (KEY_DOWN_ARROW) and y1 > 0 then xx1 := x1 + 10 yy1 := y1 - 23 xx2 := x1 - 10 yy2 := y1 -23 y1 -=1 sd1 :=10 sd2 :=10 % all sd's change direction of shoes sdd1 :=15  sdd2 := 15 end if if key (KEY_LEFT_ARROW) and x1 > 0 then xx1 := x1 -22 yy1 := y1  -8 xx2 := x1 -22 yy2 := y1 +12 x1 -= 1 sd1 :=15 sd2 :=15 sdd1 :=10  % sd's change direction of shoes  sdd2 := 10 end if if key (KEY_RIGHT_ARROW) and x1 < maxx then xx1 := x1 + 22 xx2:= x1 + 22       % SHOE POSITION IN RELATION TO CIRCLE POSITION yy1:= y1 + 5 yy2 := y1 - 15 x1 +=1 sd1 :=15 sd2 :=15 sdd1 :=10  % sd's change direction of shoes  sdd2 := 10 end if drawfilloval (xx2,yy2, sd1,sdd1,2) %shoes drawfilloval (xx1,yy1, sd2,sdd2,2) %shoes drawfilloval(x1,y1,22,22,7) %body delay (10) View.Update cls end loop

replace:
drawfilloval (xx2,yy2, sd1,sdd1,2) %shoes
drawfilloval (xx1,yy1, sd2,sdd2,2) %shoes

with:


drawfilloval (xx2 + round (sind (x1 * 10)) * 3, yy2 + round (sind (y1 * 10)) * 3, sd1, sdd1, 2) %shoes
drawfilloval (xx1 + round (sind ((x1 + 18) * 10)) * 3, yy1+ round (sind ((y1 + 18) * 10)) * 3, sd2, sdd2, 2) %shoes

dude aweosme THANK YOU. sorrry to be a burden but could you explain ?

[Tony]

in simple terms, natural walking movement's approximation by a sine wave is close enough.

alright alright alright, sorry i am such a dumb*** but , i will require a more indepth explenation as to what exactly is happening cuz i would love to use this code in future for other things. thank you

uhh... there was a link in my previous post

a sine wave -- http://en.wikipedia.org/wiki/Sine_wave is a periodic wave based on the sine functions -- http://en.wikipedia.org/wiki/Sine , typically covered in grade 10 math.

Wikipedia is fairly in-depth on the subject.

Well, i will have a fun type trying to pass this as my own genius in front of otehr people lol thank you tony, helped allot
