Examples with KeyBindingMap net.minecraftforge.client.settings.KeyBindingMap used on opensource projects

Example 1 with KeyBindingMap

use of net.minecraftforge.client.settings.KeyBindingMap in project malmo by Microsoft.

the class CommandForKey method install.

@Override
public void install(MissionInit missionInit) {
    // Attempt to find the keybinding that matches the description we were given,
    // and replace it with our own KeyHook object:
    GameSettings settings = Minecraft.getMinecraft().gameSettings;
    boolean createdHook = false;
    // GameSettings contains both a field for each KeyBinding (eg keyBindAttack), and an array of KeyBindings with a pointer to
    // each field. We want to make sure we replace both pointers, otherwise Minecraft will end up using our object for some things, and
    // the original object for others.
    // So we need to use reflection to replace the field:
    Field[] fields = GameSettings.class.getFields();
    for (int i = 0; i < fields.length; i++) {
        Field f = fields[i];
        if (f.getType() == KeyBinding.class) {

                e.printStackTrace();
            }
        }
    }
    // And then we replace the pointer in the array:
    for (int i = 0; i < settings.keyBindings.length; i++) {
        if (settings.keyBindings[i].getKeyDescription().equals(this.keyDescription)) {
            this.originalBindingIndex = i;

        }
    }
    // Newer versions of MC have changed the way they map from key value to KeyBinding, so we
    // *also* need to fiddle with the static KeyBinding HASH map:
