Random tumbleweed

[joelphilippage]

How would i be able to make a tumbleweed randomly go across the screen at different times and different directions?

I would guess that using the AGS CCS module and using characters to go across the screen.

I would probably make the tumble weed a character (unless you only need it for one room) and then put a random timer in repeatedly_execute calling a custom function;

Code: ags

//in Global Script
function get_tumbleweed(int whichway) {
if (whichway=1) { //the tumbleweed travels from left to right
 Ã, ctumbleweed.changeroom(player.room, 0, 100);
 Ã, ctumbleweed.walk(319, 100, enoblock, anywhere); //send it off screen
}
else { //the tumbleweed travels from right to left
 Ã, ctumbleweed.changeroom(player.room, 320,100);
 Ã, ctumbleweed.walk(0,100, enoblock, anywhere); //get it offscreen
}


//in script header

import function get_tumbleweed(int whichway)


//When player enters room
settimer(4, random(400)+200); //randomly sends the tumble weed along between 5-10 seconds after they enter the room


//in repeatedly_execute
if (istimerexpired(4)==1) {
get_tumbleweed(random(1));//randomly chooses one or zero
settimer(4,random(400)+200);// resets timer for tumbleweed to come in between 5-10 seconds
}

I'm not at a computer with ags so I haven't tested it or anything and it needs proper capitalization, but that's what I'd do.

good luck,

Thanks that worked except when I the tumbleweed goes off one end it comes off the other end right away.

Here's my approach:

Code: ags

bool weed_moving=false;
bool wind_changes=true;
int wind_from_right=0;

function startWeed() {
  if (wind_changes && Random(1)) wind_from_right=1-wind_from_right; // change wind dir

  // set starting position
  cTumble.x=wind_from_right*330-5;
  cTumble.y=Random(50)+20;
  cTumble.room=player.room;
  weed_moving=true;
}

function moveWeed() { 
  cTumble.x=cTumble.x+Random(2)-wind_from_right*4+1;
  cTumble.y=cTumble.y+Random(3)-1;
}

#sectionstart room_b  // DO NOT EDIT OR REMOVE THIS LINE
function room_b() {
  // script for Room: Repeatedly execute
  if (IsTimerExpired(1)) {
    if (!weed_moving) startWeed();
    else moveWeed();
    if (cTumble.x<-10 || cTumble.x>330 || cTumble.y>240) {  // weed left room?
      weed_moving=false;
      SetTimer(1, 40*(Random(2)+1));  // pause for 1 to 3 seconds
    }
    else SetTimer(1, 4); // pause for 0.1 seconds before moving weed again
  }    
}
#sectionend room_b  // DO NOT EDIT OR REMOVE THIS LINE

The tumbleweed doesn't move in a straight line and the pause can be adjusted freely.
