Street Fighter Game - How to Jump With Sprites?

[Lawlly]

Alright well I've managed to work sprites and enable walking and punching. Though still, the jumping thing stumps me once again. I'm aware I need to use booleans of course, and I tried 2 methods of jumping though still no luck with sprites.

Btw, I've already created the pictures and sprites for the jumping. I've also created the procedure that does the jump animation called Player1Jump.

And for now I've set the Up and Down arrow keys to only shift the picture, not jump.

So here's my game in its testing stages...

to jump you would need to change the y co ordinate, instead of the x. so when you press up then...

code:

%moving up loop Sprite y = sprite y + 1 exit when sprite y = 5 end loop %coming back down loop sprite y= sprite y - 1 exit when sprite y = 0 end loop

something like that

I would really like to help but as I cant see your program I cant tell you for sure what you would have to do... what i would suggest is that you input the fallowing code into your program with the coordinating variables with it, I use this code to animate my sprites but it is rather complicated

if key (KEY_UP_ARROW) then
jump := 1
end if

if jump = 1 then
y := round (y3 + velocity * tim * sind (theta) - 0.5 * gravity * tim * tim)
tim := tim + 1

and for your variables I would suggest that you go with something down these lines

var velocity, tim, tim2, theta, gravity, x2, y2, x3, y3 : real
var key : array char of boolean
var jump : int

velocity := 2
tim := 0
tim2 := 0
theta := 90
gravity := 0.02
y2 := 1
y3 := 1

so as far as all of this goes, as long as you place it in your program at the right spots, it will give you a very nice looking program that simulates gravity and angles of jumps.

Alright well here's my code if you cannot download.
