I just wanted to know how would i make a picture bounce, because my game is suppose to be like im suppose to make a ball bounce and your suppose to dodge it. But i cant make the picture bounce. this is the code so far. Can someone please correct it and re-post it again. setscreen ("graphics:1000;600") drawfillbox (1000, 800, 1000, 800, black) var numFrames := Pic.Frames ("H:/happy_face_clears.gif") % Load the picture var delayTime : int var pics : array 1 .. numFrames of int Pic.FileNewFrames ("H:/happy_face_clears.gif", pics, delayTime) var sprite, move : int sprite := Sprite.New (pics (1)) Sprite.SetPosition (sprite, 0, 0, false) Sprite.Show (sprite) loop for x : 2 .. 1350 if x > 600 then move := -610 if x > 0 then move := -610 Sprite.Animate (sprite, pics ((x div 8) mod numFrames + 1), x + move, 0, false) delay (5) % Stop sprite from moving too quickly else move := -610 Sprite.Animate (sprite, pics ((x div 8) mod numFrames + 1), x + move, 0, false) delay (5) % Stop sprite from moving too quickly end if end if end for end loop Sprite.Free (sprite) |

I never had luck using Sprites, so I'm not sure if would work for you either. But about your problem; the way yoiu make things travel in a parabola is to have an x increment and a y increment that is added to y each time through the loop. In turn, the yinc decreases by a set amount each time, so that each time, less and less is added to the y until the yinc is a negative number (making the y decrease: the bouncing object is falling). When the object reaches 0, restore yinc to an amount which will cause the y to go up (bounce off of the ground). |
