Is that all of the code? With just a code snipplet, all I can do is guess.

1. Execute Convert_Prepare every step.

If this is your camera code...

d3d_set_projection_ext(x,y,16,xto,yto,zto,0,0,1,45,1.6,1,32000);

... then these are the arguments required for Convert_Prepare:

Convert_Prepare(x,y,16,xto,yto,zto,0,0,1,45,1.6); // <- same arguments as d3d_set_projection_ext except for znear and zfar

2. Then use Convert_3d or Convert_2d depending on what you'd want to convert.

If all else fails, compare your code to the code in my example and see what you did different (or forgot).

I placed the right arguments in convert prepare script and i already tried calling it every step.
Here is my gmk: Move to mouse
Mirror: Download .gmk

Maybe you can find whats wrong :/ Sorry for very messy, unorganised or nooby code :/

Fixed and working: link.

I changed a couple of things:

• Your grass texture mas making my eyes bleed so I replaced it with a nice one from my texture archive.
• I put in the conversion scripts as used in this example and removed yours. (Obviously I prefer the scripts used in this example)
• I fixed the movement of your player. This prevents the camera from being super-jumpy when standing still.
• Aspect is defined as width/height, not height/width!
• I made the click commands happen from the camera object, this is easier programming when using conversions.

Enjoy!

Thankyou very much! sorry i didnt post straight away, school has been holding me up. thanks again.

Thank you for this example, but do you have any ideas on how to modify this method to be used to detect a point on a rotatable surface at varying z values and to have the mouse independent of the camera? I'm making an animation editor for personal use and at the moment I'm using a dropdown list to select parts to edit which is significantly slower than simply clicking.

For this you would need to use a collision dll and cast a ray against your model. In theory this could be combined with this example, first use 2d-to-3d to find a direction and then cast a ray using the collision dll.

Awesome, works perfect!

nyc example but i have a question...
if want to add buttons in screen which is mouse clickable ....what can i do...the cursor is stuckeD in the centre of screen..

[jflorek]

This script was probably meant for an FPS... although there is a similar version of it by icuurd<some#s>, although I think it was actually made by yourself... Idk where it is though.

[Phantom107]

The mouse is being reset to the center of the screen. If you stop it being reset, you can do the 2d-to-3d on every position on the screen as you see fit.

As for the clickable buttons, I am not sure if you want them locked in place or hovering above 3d items and such. You won't need these scripts for the former.

[ShubhamBansod]

Ohh.....:'((
ok
now i m telling what i,m working on....
i m creating a 3d room creator with rhe help of your example...as it was the bestest for pointing in a 3d field...i add a odj_cpu which create a 3d object when mb_left is preesed ....when we press key's' it saves the .3dlvl file which contain the x,y,z location of the object ...any by preesing key'l' it will load it.....then i realise if i add some buttons on screen for save and load by d3d_...._ortho ...it is good....please panthom107 ...your the only one who can help me ....do some thing....soon i will,upload my example...for ur help...:'((

[Phantom107]

I don't understand your question?

- You can stop the repositioning of the mouse by getting rid of the code that does that. It's in the step event.
- You should call an ortho projection when all other drawing is finished in the room. Then draw your 2D buttons.

[programmmer5]

OK i see that it works with

d3d_set_projection_ext()

but is there anyway it can work with just

d3d_set_projection()

?
