[1.7.10] Freeing cursor on keypress

[Roboguy99]

I want to make it so when the player presses a key (my keybind is already working) the cursor is unlocked from the centre like when you use a Gui, and locked again when the player lets go. How would I do this?

It REALLY depends on what should happen during free-cursor time. Present whole idea.

So the idea is when the player holds down a key, a HUD appears showing items stored in an inventory in a GTA V-style weapon wheel. The rendering is all done, but I'd like the user to be able to move their cursor over one of the options and click (or move the cursor and let go of the key without clicking, doesn't really matter). So I need to know the mouse co-ordinates and possibly when they click essentially.

Can't you just open/close Gui on down/up button press? And on unpress get position of mouse related to center which will tell you to what side you hovered (e.g hovered to the left to pick left slot)?

My weapon wheel is rendered straight onto the HUD because it was easier to dynamically adjust the size this way. Would opening a GUI still work, and would I just have to open it client-side?

should work since ur gui isnt doing anything on server side. just send a packet for selecting the weapon

K: well for a start you'll want an event set to

 

@SubscribeEvent

public void onRenderTick(RenderTickEvent event){

if (event.phase == Phase.START&& your boolean or whatever ){

                        Minecraft.getMinecraft().mouseObject.objectMouseOver.typeOfHit = MovingObjectType.MISS;

                }

        }

This will prevent the player from being able to select anything. I think theres a boolean or something that handles if the mouse is rendered/moved, but I'm not too sure

 

Edit: Look for something around these (not accurate names)

org.lwjgl.input.Mouse.create();

this.mouseHelper = new net.minecraft.src.MouseHelper(this.mcCanvas);

Lol forget all of that.

 

Its really easy

 

    Minecraft.getMinecraft().setIngameNotInFocus();

 

Plz give me thx

This seems like it should work. I'm going to have to play with it a bit, because you have to manually re-set the focus when the key is no longer pressed.

If the other method doesn't work, I will use a GUI. It sounds easy enough, although I'll need to find out how packets work.

Ok so I can unfocus the game without a problem, but making sure it's focussed again when the button is released is quite hard: a) I don't wan't to keep the game focussed even when other HUD elements (i.e the chat or pause menu) are trying to open because this breaks them and b) I want my HUD element to appear for more than one frame.

 

I suppose what I'm asking by hinting at my problems is how do I toggle the focus on button press without keeping it stuck in focus the whole time the button is not pressed? Would I need to write a keyUp method (this could do with being implemented into Forge, I might look into writing and pushing it when I've got time), or is there a better way?

 

Here's the whole class (mostly) to (maybe) make life easier:

 

public class EventsHandler extends Gui
{
private static final int RADIUS = 100;
private static final int ITEM_RADIUS = 85;

private static final int TOTAL_SECTORS = 20000; // Total number of small sectors, essentially circle definition

private Random random = new Random();
private static final Minecraft minecraft = Minecraft.getMinecraft();

private RenderBlocks renderBlocksRi = new RenderBlocks();
private boolean renderWithColor = true;
private static final ResourceLocation RES_ITEM_GLINT = new ResourceLocation("textures/misc/enchanted_item_glint.png");

private boolean keyPressed, keyPressedAndWasDrawing;

@SubscribeEvent(priority = EventPriority.NORMAL)

	{

						}
					}

					ItemStack[] inventoryContents = inventoryContentsList.toArray(new ItemStack[inventoryContentsList.size()]);

					float x = event.resolution.getScaledWidth() / 2;
					float y = event.resolution.getScaledHeight() / 2 - 15;

					double multiplier = this.TOTAL_SECTORS / items;

					// Brace for ugly maths! TODO make maths look less ugly

							for(int i = 0; i < items; i++) // Draw circle

								{
									double t = 2 * Math.PI * (float) j / (float) this.TOTAL_SECTORS;
									GL11.glVertex2d(x + Math.sin(t) * this.RADIUS, y + Math.cos(t) * this.RADIUS);
								}
							}
						}
						GL11.glEnd();
						GL11.glEnable(GL11.GL_TEXTURE_2D);
					}
					GL11.glPopMatrix();

					double radiansPerSector = (2 * Math.PI) / items;
					double offset = 0;
					if (inventoryContents.length % 2 == 0) offset = radiansPerSector / 2;

					for(int i = 0; i < inventoryContents.length; i++)
					{
						double radians = offset + (radiansPerSector * i) - (Math.PI / 2);

						double itemX = this.ITEM_RADIUS * Math.cos(radians) + x - 8;
						double itemY = this.ITEM_RADIUS * Math.sin(radians) + y - 8;

						this.renderItemIntoGUI(minecraft.fontRenderer, minecraft.getTextureManager(), inventoryContents[i], itemX, itemY, true); //Copied and changed to accept doubles instead of ints
					}
