Making an interface question

Game Engine Game Engine Support and Discussion
#1

I made a point an click interface. I used a plane that has a texture mapped onto it. On this texture there are several images, above each image I have a smaller plane which are parented to the textured plane. It works by putting cursor over image and clicking. Here is my problem. The objects are too big. If I scale the plane that is over image, it works but still too big,I can’t scale plane too small. Normally I would just scale an empty but I can’t use a mouse cursor for an empty. Hope I did not confuse with my question. I never made an interface before.

I’m not exactly sure what you mean.
Changing the pivot point can help with local scaling:

#3

Check you’re in Perspective Mode. There is a bug in camera.getScreenRay() in orthographic mode - and this bug may (?) also be present in the mouse over sensor.
An image of your setup would be good to help diagnose the problem.

#4

You can temporarily make the planes visible to see where they are in game.

#5

How can I scale my objects without changing the physics? If I scale empties everything works fine but I am using a plane. Can I use an empty to point and click?

#6

What are you scaling?
What is too big?

Just now I find your description too confusing to understand the cause of your problem.

#7

I know my description is confusing so I included a pic. Normally I would use an empty in the scene. If my object was too not the size I wanted I would scale the empty, problem solved. Look at the image. When I try the interface the object is like 5o times larger than I want, if I scale the plane in the red circle (I made planes visible) it helps but I can’t scale that much. I appended the interface to test it to my project. Any thoughts? This is something I really don’t need but thought it would add a nice touch.

still no clue what you want.

the plane smaller or bigger?
scale stuff in edit mode, or ctrl+a and apply scale.

the image smaller/bigger?
go to uv editor and make the uv’s smaller or bigger

why not put the picture you like as a button on the button itself?
then it will cover the whole plane and you can scale it to the size you like.

#9

First. in the physics panel set collision type to static and collision bounds to ‘triangle mesh’…I would not recommend this with a high poly count, but this is absolutely fine based on your image…

Second, scale each plane to the desired size and outside of edit mode press ‘ctrl+a’ > and select ‘scale’…do this for each plane…

Lastly, report back and let us know how it goes or if you have any other issues.

EDIT: @Cotaks: we posted at the same time :)…well you were first I guess :slight_smile:

If I understand correctly the planes should cover a much smaller area?

I mean when it is scaled down 50 times you get a really tiny plane.

#11

I guess I am not explaining myself very well. I want the image the same size more or less and those planes big enough to cover the images below the planes. The problem, when i click on the plane the object is HUGE, I want it smaller object but I don’t want to scale the object because it messes the the physics of my object in the scene.
I found the problem, it happens when I parent the small plane to the larger image plane. When I clear the parent it works normally. Thanks for your replies

child objects inherit the transforms of the parent. if child is 1m at a 1 scale and parent is scale 2, the child will then be 2m.

#13

So if this is your problem, apply scale to the objects with ctrl+a that wil set the scale ratio back to 1 for the selected object.

hehe, i noticed when i posted my message yours was directly visible below me, so we should have pressed the submit button at a second or less of each other. Don’t see that happen to often haha

#14

Since I have it working wanted to ask one more question on this. I am setting it up so by pressing a key my interface will appear at top of screen. I wanted to know if when I click on the object image at top of screen can I make it so my object will enter scene where i want it to, like at the center of scene.

Sure you can.

Play an animation that moves it down.

#16

I meant hooking it up to an empty but your idea will work as well.

digiman

#17

You can parent the menu to an empty and animate that empty.

When you use an overlay scene, you can move/animate the camera of the overlay scene as well.
