simple "go next" action script?

[eilidhb]

I am trying to create a simple slide show, i have set up the different slides with labels and i want one button to go to the next slide and one to go to the pervious.

It seems simple but i cant seem to find a code that works.
something like...

on release go to and play "next"

there are too many slides to put in the individual name of each label. so a simple next button would be ideal.

any ideas?

are you moving the playhead along a timeline ?
if so, use -
nextFrame(); // goes to the next frame and stops
prevFrame(); // goes to the previous frame and stops

ActionScript 2.0 Language Reference >
ActionScript language elements > Global Functions > nextFrame function
an example of controlling the timeline with keypresses is shown here.

hi thanks for ur reply. I need the playhead to go to a specific label because not all labels are the same number of frames apart. its just a simple slide show, but some of the slides need to run for more frames than others, therefore if i could get the playhead to jump to the next label that would be ideal. there are too many to type in individually the label name.
any ideas?

if you are going to navigate by labels, at some point you are going to have to
bite the bullet and make a list of all of the labels in use

prolly easiest to use an array and a variable

arrLabels = ["label1", "label2","label3"......]; // array of labels
var id =0; // variable

next_btn.onRelease = function(){
id <= arrLabels.length ? id++ : null; // don't go past last label in array
gotoAndPlay(arrLabels[id]);
}

prev_btn.onRelease = function(){
id > 0 ? id--: null ; // don't go past first label in array
gotoAndPlay(arrLabels[id]);
}

im a beginner so thats looks really complicated to me. if you have a spare minute can u explain it a bit more. thanks a lot!!!!

variable id starts at zero - id=0;

next button has id++, this is id = id+1, so id=1;
in the array - arrLabels[1] = "label2"
so the button release sends the timeline to "label2"

previous button has id--, this is id = id-1, so if id was 5, it becomes 4
in the array - arrLabels[4] = "label5"
so the button release sends the timeline to "label5"

the ternary operators < ? : > are used to prevent the variable id
going outside of the limits of the array

any help
