I am using open layers 4. I am moving and stoping marker animation as this example without any problem. But I want to add pause and continue functionality to marker also. I edit some variables and endeavor on the issue with these functions. When I call continueAnimation
function at first, the elapsedTime
parameter become negative and give exception on moveFeature
function. When I secondly call the continueAnimation
function. It is working as expected. It is looking like kind of javascript implementation issue.
function pauseAnimation() { animating = false; //I hold elapsed time globally var index = Math.round($("[id='rightfrm:tbv1:txt1']").val() * elapsedTime / 1000); (geoMarker.getGeometry()).setCoordinates(line_coordinates[index].lc); map.un('postcompose', moveFeature); } function continueAnimation() { animating = true; now = new Date().getTime(); now = now - 10000 + elapsedTime; // --10000-- for negativeness geoMarker.setStyle(null); map.on('postcompose', moveFeature); map.render(); }

I found my problem. It was a logical error. Pause and Continue working now.
now = new Date().getTime() - elapsedTime;
Anyone can use these functions for Pause/Continue functionality.
