Easy jump example

[ChebbyShabby]

if you ever wanted to make your sprite jump with simulated physics, i've whipped up a quick example here: http://www.MailFreeOnline.com/uploader/7004BA98.zip

and for the slightly more advanced user (involves platforms) -- VERY buggy, quickly done:

(push space bar to jump)

Code: Select all

If OpenScreen(640, 480, 32, "Eraser") 
  LoadSprite(0, "Square.bmp") ;Change this to the location of your sprite 

  SetFrameRate(60) <------------- insert this line here

  Repeat 
    FlipBuffers() 

Might I suggest a small change to your code.

See the line above.

Other than that, very good. Thanks for sharing.

ah yes... the frame rate. my bad

I'm curious, why do you suggest SetFrameRate(), Derek?

[Derek]

Because the example was moving so fast that it needed to be slowed down. Could of put a delay(1) in the loop or flipbuffers(1) I suppose.

[Kaeru Gaman]

on most systems you can leave the SetFrameRate() out,
but on some systems it will move too fast without it.

its a rough solution, but it works.

but since FlipBuffers() will use 100%CPU while waiting for the next frame,
the better solution would be to put the whole movement under time-control.

best solution would be seperate threads.
one is timer-controlled and does the movement of the objects,
a second does the display and just runs on maximum framerate, or with a little delay...

[Derek]

It was just a quick fix without having to go into timing issues and such, the example was only a quick little program and didn't warrant any major overhauls. Just something to slow it down a bit.

Double post - sorry.
