[HELP] Projectile Direction

[Thomas_Nightfire]

Hey there!

Is there a way to set projectile a direction? I've tried to test Rocket, but it always fly to direction of player camera... Tried to set rotation of projectile, but it only changes rot of it, not the direction. Please help!

Hello, did you try to set the velocity of the projectile when creating it ? you can do it in optional arguments of createProjectile()

I've tried to set velocity, but idk how to set proper velocity to fire in certain XYZ point...
And even using velocity arguments, rocket sometimes flies not straight: after a few seconds changes direction to player camera or whatever I can't understand
Please help!

Projectiles with an owner have their orientation pre-set based on the camera rotation.

Setting the orientation after the projectile creation, will only work when all clients are applying the same adjustments.

 

AFAIK only a full overwrite of the behaviour and synchronization will solve that problem.

Can u please write a simple example how to overwrite it's behaviour?
And if rocket blows up something, who's be responsible for it? Owner?

You can for example create an object (server), use projectile model:

Move the object (server):

And when it hits something (client), checking with this function every frame:

https://wiki.multitheftauto.com/wiki/OnClientRender

 

Than you trigger to serverside and make an explosion:

And yes it is not easy.

 

 

 

If not an overwrite:

• The player that creates the projectile:
  
  projectile createProjectile ( element creator, int weaponType [, float posX, float posY, float posZ, float force = 1.0, element target = nil, float rotX, float rotY, float rotZ, float velX, float velY, float velZ, int model ] )
  https://wiki.multitheftauto.com/wiki/CreateProjectile
   
• If the vehicle creates it, the owner should be either the vehicle controller or the syncer.

Nice... thought another way exists, but thank you
