<h1>ol-games: Sprite path</h1>
|
|
</a>
|
|
<div class="info">
|
|
This example show how a sprite can follow a path.
|
|
<br/>
|
|
You can use the <i>ol.Sprite.setPath()</i> to set the path to follow. Then just call <i>ol.Sprite.move()</i>
|
|
in the game loop to have the sprite moving along the path.
|
|
Use <i>ol.Sprite.stop()</i> and <i>ol.Sprite.restart()</i> to control the movement.
|
|
<br />
|
|
Listen to :
|
|
<ul>
|
|
<li>
|
|
<i>change:direction</i> event to know when the sprite take a new segment
|
|
</li>
|
|
<li>
|
|
<i>destination</i> event to know when the sprite reach the final destination.
|
|
</li>
|
|
</ul>
