Follow path in steps ?

[akhad]

Anyone know of any way to make your object follow a path in incremental steps, rather than following the whole path in one go ? For example, your object is assigned to a circular path, and you want your object to follow the contours of the path *only* when you press a key. With no key pressed the object stays at its last position, ready to move on aqain when the key is pressed once again.

Is not possible now, but I will put in my task list.

Currently you could do this with some code:

First make a variable on the actor you want to go in circles called "allowMove". Then use these script events:

on key down:

Code: Select all


circle_actor.allowMove = 1;



on key up:

Code: Select all


circle_actor.allowMove = 0;



on circle actor draw event:

Code: Select all


if (allowMove)
{
    angle += 0.1; // determines the size of circle
    directional_velocity = 2; // determines the speed
}



hope that helps

Thanks for the replies. I was thinking that the path curve could be accessed in a similar way to the animation frame process. i.e just like you can jump to frame 25 of a 50 frame animation you could jump to step 25 of a 50 step curve/path. Although paths don't really hold `frames`as such they are are created over a set time sequence and the nodes are similar to keyframes in cgi animation. A keyframing system would be great, each keyframe could hold extra data like curve type (bezier/linear etc) and even hold `delay` values so your object could stop for x amount of time at individual keyframes/nodes.
morcior, that looks interesting. I'll give it a go when I get back on my GE dev machine. Karma to you sir !
