Select point on terrain using mouse
Blitz3D Forums/Blitz3D Beginners Area/Select point on terrain using mouse

| I can see how I can select an entity already placed using CameraPick() What I want to know is how do I use MouseX/Y and then translate the viewport coordinates to terrain coordinates so I can select a place on the terrain. I want to do a similar thing to populous where you can click the landscape to create a hill. I also want to be able to move the camera around. I had a look at the code archive and found some code that purported to do what I wanted but only seemed to work when the camera was looking directly down on the scene which isn't what I want. I know you can use a cameraproject to get from 3d to 2d there must be a way to do the reverse? Any help would be greatly appreciated. Thankyou! |

| PickedX, PickedY and PickedZ should help you. Have a look at the help supplied with Blitz as it has a good example of how to use this. Also here is a link that might help you... http://www.blitzbasic.com/Community/posts.php?topic=49109#546423 |

| Thankyou, the example you linked to was nice and simple. I had tried that but had forgotten to make my terrain pickable. Now it works. Hooray! |
