Darkmod,
This solution is good, but I wanted the player to move in a smooth way, I tried to apply force on it, but it accelerates instead of maintaining a speed continues and is jumping even though I configured the “bounce = 0”.
could you still help me ?

Brent,
unfortunately setting the property “Body Active = true” did not work.
But I realized that when I I reduce the value of the variable “dx”, the object does not pass through the wall, but it is slow and I do not know how to set intervals faster than the object back to normal speed.

If you add 5 to body.x, it probably jumps inside another object. If you want to go 5 pixels ahead in a single frame, then add velocity to your body ( it requires the velocity in pixel/second, so if your game runs at 60 fps then set vx to 300).
In the next frame you can fix the body position if needed, but collisions will be detected as expected.
I’m using this technic in my game, and works very well. [import]uid: 88330 topic_id: 30344 reply_id: 121916[/import]
Macc,
I configured the “fps = 60” in the config file,
this worked in the Corona Simulator but was too slow in Android.
was that what I should do?

Darkmod,
The problem of sticking into the wall was solved.
and the problem of the severity of has also been solved.
But when the player is in the air and moves in any direction, its speed starts slowly and then accelerates with the method “applyForce.”
Sorry to ask so many times.

You mean the perfomance of our game is slow? If previously you used 30fps, you can still use it, just add 150 to vx instead of 300.

Macc,
The game works in “fps = 30”, but i still do not know which variable is “vx” that you are referring to.
I’m sorry to ask this.
Thank you, [import]uid: 95474 topic_id: 30344 reply_id: 122052[/import]
Jesseh:
http://docs.coronalabs.com/api/type/Body/setLinearVelocity.html
In your case (30fps):
myBody:setLinearVelocity( 150, 0 ) – right
myBody:setLinearVelocity( -150, 0 ) – left

Macc,
Firstly thank you for your attention;)
the problem of the collision has been resolved, but now gravity does not work well.
the player falls slowly and when I increase the value function keeps the speed, and the body does not accelerate with gravity.
I configured like this:
player:setLinearVelocity (dx, 0)
and put this function in the update() function above.
how do I configure “setLinearVelocity” without changing gravity?
Thank you again, [import]uid: 95474 topic_id: 30344 reply_id: 122093[/import]
You need to play around with some of the physics settings unlit you get what your looking for.
[lua]physics.setVelocityIterations( 24 )
physics.setPositionIterations( 10 )
physics.addBody( playerbody, “dynamic”, { friction=1, bounce=0, density=6 ,filter = { categoryBits = 1, maskBits = 1} } )[/lua]
and i would not get too crazy with the gravity … try adding more density to the player object. [import]uid: 7177 topic_id: 30344 reply_id: 122103[/import]
Darkmod,
Thanks for the tip, but gravity is still the problem in the method “setLinearVelocity.”
The player moves well side to side, but slowly falls.
And the method “applyForce” worked well, but the player starts slowly and then accelerates motion, I would like it moved around smoothly like in games: Mario, Sonic, Megaman … for example.
Thank you again. [import]uid: 95474 topic_id: 30344 reply_id: 122372[/import]
Jesseh, here’s a quick mock up. By no means is it perfect but should get you going to the right direction. There are tons of physics options/settings I recommend reading up on them and get a basic understanding how to use them. By no means would I use my d-pad controller I would rate it as a F. Take note how I use velocity ‘setLinearVelocity vs applyForce’. Play around with all the setting to get a better understanding of the physics world. Friction,bounce,density,Force,Gravity…………. And so on.

got it!
I applied a force opposing the movement of the character when he is in the air and uses the “applyForce”, but then the character could not cross from one tile to another, so I added a little “bounce” and it worked!
this will help me us for upcoming games that I do.
Thanks for everyone’s help here,
