Following a line Without using paths?

[ag07]

How can I get an object to follow a line, Without using paths? I want the object to follow lines formed from random coordinates, based on mouse clicks. So a path laid out before the game runs is not suitable. Is using paths the only practical option?

Thanks

Howdy, ag07,

Did you look up "Paths" in the manual's index? The last bulleted link on the page should say "Changing Paths," and that page reads, "In GameMaker: Studio you are not just limited to the paths that you make using the Path Editor. There are a number of functions that can be used to manipulate and change those paths at run-time, or to even create new ones and then change and manipulate those," before listing a bunch of functions that should interest you.

The manual is your friend. I hope this helps,
Bob $:^ ]

Store each mouse click as a waypoint and use the direction from the current position to the next waypoint as direction and set the unit's speed.

Thanks to both of you. I guess I missed that last section of the paths manual..

"Store each mouse click as a waypoint"....how do I do this? Please give an example in code

thanks

direction=point_direction(x,y,waypointX,waypointY)

just store some points in an array and load them into that

 

[ag07]

if (array_pos >= 1) { //array_pos shows current element of array called "point"
image_angle = point_direction(x,y, point[array_pos - 2], point[array_pos - 1]);
direction = point_direction(x,y, point[array_pos - 2], point[array_pos - 1]);
speed = 1;
}
}

The above code works.

Thanks again
