Problem with gravity and move

patapple

hi everyone,

i'm working on a new game but i have the scene gravity Y set to 200 and i have an actor is moving on the x axis, but if I turn off the move behavior the actor fall down (affected by gravity) and if i turn on it doesn't work, it only move right. why?

i know it'a stupid question, but i never created a game like that.

thanks

Something you might want to do is put an accelerate behavior in each actor you want to be effected by gravity. Do that instead of having the whole scene have gravity.

patapple

it doesn't work. I insert the accelerate behavior to down and a move behavior to the right. but it doesn't work.

Any idea?

here is a screenshot of my rules.

Just play with the settings. Try different acceleration values.

The move behavior will override gravity.

Use change velocity or change its self motion linear x attribute.

It should work fine. I just tested these rules and I could move along the "ground" actor:

@tatiang

Nope, thats because your moving along a ground actor. Add a jump button to it then jump and move and watch what happens. Move behavior will over ride gravity. Thats how the move behavior works, i talked to the gs guys a long time ago about this.

tatiang

Right, I would use change velocity instead of Move, but the rules did work for simple movement. You're right about jumping.

patapple

Now i change the move behavior with a change velocity and it works. Now i create a button and a jump attribute, but what behavior can i use?

JohnPapiomitis

to jump change attribute self motion linear y to 400 (you can change the 400 to whatever you want to adjust the jump height)

Thanks a lot!!!

sorry but i now i would like to change the game system. Now i have my main character stationary, and the ground is moving to the left (to simulate the run). I would like to add the gravity to do the main character collide the ground but here are my problems:
1) if i try to add the scene gravity the ground fall but i can't uncheck the movable box
2) if i try to add an accelerate behavior to the main character it push down the ground.

I hope you can understand my bad english...

@patapple .. can you turn moveable off on the ground and interpolate its movement? If not you may have to set its rotate off, constrain its Y position to what you want and I would throw 10000 in it's density for good measure.
