Questions about Lemur Mouse Listeners

[icyboxs]

I found out how to make a multi-select box from here

RTS Selection Box

There is a simple way to get a correct selection. The perfect match is more tricky. You’re trying to translate your selection rectangle from screen space to world space. You will find it much easier to tranlate your unit position from world space to screen space. Now you just have to check if unit screen projection is inside you 2D box. Does that help? You’ll find my implementation for OpenRTS at the bottom of this class Don’t hesitate to @mention me if you need more RTS code tricks

CursorEventControl.addListenersToSpatial(simpleApp.getRootNode().getChild("MapNode"), new DefaultCursorListener() {}

I’m using this code which causes the mouse to not detect off-map triggers.

Is there any way in Lemur to make a callback without touching anything?

Maybe I should implement it in ActionListener and AnalogListener?

If anyone has any ideas please reply to me in this post! thank

Yeah, if you want your selection box independent of other geometries, you should use a standard input system.

Pseudo code:

analog input:
    if primary box corner pos != null
        second box corner pos = mouse position
        update selection box geometry
state input:
    if mouse button is down
        primary box corner pos = mouse position
        attach selection box geometry
    else
        primary box corner pos = null
        detach selection box geometry

I hope that helps!

Even through Lemur you can listen to the raw mouse buttons and mouse axis movements.

InputMapper (lemur 1.15.0 API)…-

Mapped to things l like:
http://jmonkeyengine-contributions.github.io/Lemur/javadoc/Lemur/com/simsilica/lemur/input/Axis.html#MOUSE_X

But yeah, these things are always going to be pretty manual.

Do you have a demo of how to use InputMapper? I might need it, there is only a description in the documentation, I tried to use it but failed …

Lemur Gems #1 explains how to use the InputMapper.
