Detect Mouse-Move in open GUI


Recommended Posts

Hello Guys, I'm kinda new to Forge-Modding, but I'm trying to create a Addon for IC2. Right now I got a custom Machine with a Own GUI'n'Stuff.

So currently my Machine has Bars where it shows you the Level of the Stored-Energy (Displayed by a Vertical Bar which filles up). And I want to add a Text-Box to it when you hover over it.

Some other Mods have this feature and it's kinda nice, that's why I wanted to implement it. But I got a Problem with detecting if the Mouse Moves :/

I already tried mouseMovedOrUp(), but it somehow only triggers by Clicking in the GUI (I check it in at the beginning of the Method, not after checking the which).


So has someone an Idea how to keep track where the Mouse is?

If you extend GuiScreen

public void drawScreen(int mouseX, int mouseY, float par3)



If you extend GuiContainer

public void drawScreen(int mouseX, int mouseY, float par3)

public void drawGuiContainerBackgroundLayer(float par1, int mouseX, int mouseY)

public void drawGuiContainerForegroundLayer(int mouseX, int mouseY)



Check if the mouse is over the bar.

mouseX >= energybarX && mouseX <= energybarX + energybarWidth && mouseY >= energybarY && mouseY <= energybarY + energybarHeight

Then draw your tooltip
