Physics Test

Remember Lunar Lander?

A quick example to show physics in action. Control the lander with the arrow keys and land on the platform.

Try it HERE.

BTW I know the Physics.VelocityY is exposed but I can't seem to get it to display :(   Without it, I can't really calculate the landing velocity, which would determine if it would crash or not. Anyone else tried?

Pretty fun. :P

Why even use physics for this? The whole point of physics is for realistic interactions between moving objects. What you have here can easily be done with just 2 variables, or more easily, the custom movement behavior. Using the physics object for this isn't efficient. Not trying to be rude or anything; just trying to make you a better programmer! <img src="smileys/smiley17.gif" border="0" align="middle" />

The point of it WAS to test the physics, that's all it was for. I wanted to test the Y, Y and Angular velocity parameters, and this seemed the easiest way.

nice exemple

it works, and only this is important to me. I'm not a programmer and I'll never be. <img src="smileys/smiley1.gif" border="0" align="middle" />

how to set gravity power for physics?

Check these 2 articles from Ashley. They explain all about the physics behavior. Very useful :)

Question, is there a way to make some objects heavier than others? I am guessing not by gravity though. My best guess, would be to set density/weight or something of the sort?

zenox98 awesome! I love these simple games that still have substance to them and I always loved that old game!

— I thought that's what the density parameter was, no?

Me too. This was just something to test out the new physics behavior. Now updated to include zoom when landing and explosions (wooooot!) :)

BTW Still can't retrieve the physics.velocityy or x values. Anyone else tried?

velocityX.Y_test.capx

Simply Sprite.Physics.VelocityX or Sprite.Physics.VelocityY expressions.

It works fine when I preview this example.

Thanks Kyatric.

I now know what I did wrong. I tried to set a Global variable to the Y-velocity, then append it to a text field. It doesn't work that way. If I use an object instance variable instead, then I can both display it and use it in a calculation. Sorted!

Thanks for checking for me :)
