Ville, i recommend you to open a category on the forum with the name of Newcomers
So they can ask all their noobie stuff

Hi jonaspm,
Attached is a example of the easiest way to do this.
What kind of game are you trying to make?

Hi jonaspm,
just a small tip how to achieve more natural behavior. In the example from Kjell change the following expressions in the OnUpdate section of Model:
Code: Select all
CurrentModel.RotationVelocity.Z = 0; ---> CurrentModel.RotationVelocity.Z *= 0.9;
CurrentModel.RotationVelocity.Z += 1; ---> CurrentModel.RotationVelocity.Z = 1;
CurrentModel.RotationVelocity.Z -= 1; ---> CurrentModel.RotationVelocity.Z = -1;

@Rado1
You probably don't want to mix framerate dependent ( *= 0.9 ) and independent ( Velocity ) techniques though. Since I'm using SyncedWithMonitor the deceleration will be slower on monitors with lower refresh-rate / devices with lower performance, while the effective rotation velocity will the constant regardless of framerate.
Also, by changing "-=" and "+=" to "=" the rotation won't stop when you're pressing both left and right at the same time ( which I personally find desirable ).

Kjell - yes, you are right. This was just a simplified "didactic" example of how to achieve such an effect easily. In reality, I would use FPS-independent solution, similar to the attached one. (Optionally, I would maybe access rotation directly, not by velocity.)

im working on a 3D space shooter, however im more than newbie in ZGameEditor, so im having lot of questions and doubts e.e
i changed from programming the entire game in BASIC to ZGE... i think is faster this way

Hi jonaspm,

Depends a little on how you want to handle this ( technically ). A common way is to hide the Windows cursor and show a sprite instead* Attached is a example on how to do this ( albeit a little awkward, the Font component is actually the easiest way to pull this off ).
*The windows cursor will only be hidden in a standalone executable, not in the Editor.

ok, so i tested it, and works perfectly, however i have a problem, the image shows with black background, and it shouldn´t since the background is trasparent (.png alpha channel)

Simply change the Blend property of your cursor Material into "Alpha/OneMinusSourceAlpha"
