sprites scrolling
« on: May 30, 2010, 05:08:27 pm »
alright, I need someone to help me make a scrolling BG for my title screen

Code: [Select]
[FFFFFFFFFDFDFDFD]->Pic1
dispgraph
vertical +
for(A,0,95)
pt-off(50,A,Pic1)
pt-on(rand^96,A,Pic1)
end
This is supposed to be a rain/snow effect, so it needs to draw the sprites multiple times, and scroll all at once. Please help.

Put your Vertical + command in a Repeat loop.

it doesn't display the sprites actually
edit: whoops.. I didn't put a dispgraph in there XD
edit 2: yeah.. didn't make a difference. It's only displaying ONLY one sprite scrolling at one time.. and actually that's all it displays, is just one sprite, then it ends.

The program should look like this:

Code: [Select]
:<data goes here>
:<For loop for drawing the sprites here>
:<Repeat loop WITH DISPGRAPH inside here>
And you might just be better off making a Pic of the rain and/or snow and showing that instead.

Well what is this sprite you are adding in?  Your sprite is mostly black so if a new one is being displayed every frame the screen would get black pretty quick.

if I remember he wanted to be able to do stuff like in the STARSHIP demo included with Axe Parser and the first program shown in the tribute video. Just not with that many sprites at once
