Hi I got school project to code game in JSF but I struggle o lot with keyboard.
I want to call method moveCubeUp()
from cubefield to move UP if user press keyboard UP and then update form and do this to all 4 directions.
I tried javascripts, jQuery, primefaces hotkey
This is in my xhtml:
<div class="game">
<h:form id="form">
<g:cuberoll value="#{cubefield}"/>
Cube X: <h:outputLabel value="#{cubefield.getCubeX()}"/>
Cube Y: <h:outputLabel value="#{cubefield.getCubeY()}"/>
</h:form>
</div>
and cubefield:
@Named("cubefield")
@SessionScoped
public class Field implements Serializable{
public Field() {
... constructor
}
public void moveCubeRight(){
... do stuff
}
I think you can try to trigger it with ajax. It should look like this :
`<f:ajax event="onkeypress" execute="keyCode" listener="#{bean.listener}" />`
Then you can get the key in an hidden input.
`<h:inputHidden id="keyCode" binding="#{keyCode}" value="#{bean.keyCode}" />`
