Why does actor rotate after spawning another actor?

GabTobBen

The shooting actor can be rotated through controls to a certain position. When a button is pressed it can spawn another actor. However, when this second actor is spawn, the first (i.e. shooting) actor gets rotated around (even though no controls are active and the angle for the shooting actor does not change, which I checked that with display text. So it seems the shooting actor gets bounced around by the spawning actor, but I can find nothing in the physics settings that would make this happen. What can I do to fix this?

Welcome to the forums. Do you have a collide behavior on either actor? If not, they won't directly affect each other.

Without seeing your rules, it's hard to know why the spawner actor is moving after spawning.

Hi Tatiang. No Collide behavior on the shooting actor, and only one colliding rule on the spawned actor, but with another actor not the shooting one.

I can share the rules if that helps.
Many thanks in advance

Post a screenshot of your rules, if possible. Instructions are in my signature below.

Had started writing down the ruels while posted. Hope this can help. Here the rules for the actors

attributes
DigitalWater (boolean) : spawned actor on screen
WaterFlow (boolean): actor can be spawned
X (real): attribute that stores the touch X position

Spawned actor:
accelerate direction 0 relative to actor, speed 300
when collision with (third actor: unrelated to shooting actor) destroy
attribute DigitalWater to False (ie no spawned actor on screen)

Shooting actor
rotate to (constant_a-constant_b*X) relative to scene, speed 200
when WaterFlow true, change attribute DigitalWater to true
Spawn actor (ie above actor) in back of actor, direction 90 relative to actor (rest is 0)
change attribute WaterFlow to false

I don't see any reason that the Shooting actor would rotate other than however it is currently rotating with (constant_a-constant_b*X) relative to scene, as you listed above.

Double-check that you haven't unlocked any of your actors on the scene (if you double-click on an actor on the scene itself you should see the lock symbol). If you have, try deleting and re-adding the actor to the scene. Unlocked instances have different rules from their locked prototypes that appear in the Actor inspector pane.

I checked whether any of the actors are unlocked, however, they are all locked.
Anything else that could help?

What does this mean . . . .

. . .

rotate to (constant_a-constant_b*X)

I know you say it rotates "through controls", but could you be more specific, what kind of controls are you using ?

GabTobBen

Now it seems fixed, what I did is remove the shooting actor, introduce a new actor and gave it the rules of the 'old' actor.

Help! I am not succeeding in getting the shooting actor to stop spinning when it spawns an actor. I thought it was fixed, but it started again, after which I tried tons of different things but nothing keeps the shooting actor from spinning. I have posted the rules on this link. Hope Socks or Tatiang,you can still help? ?

Many thanks to Bob from GameSalad for helping to solve this. Solution was to use self.rotation instead of the command behaviour 'rotate to angle'.
