Particle Spawn on Object

[KevDoesArt]

Ok I have a particle system set up to produce leaves out of a tree. All the code is set up correctly and I have it so that the tree spawns the obj for the particle system on creation but I cannot get the emitter to be on the tree. I set the create code for the obj to x = obj_tree.x and the same for y but still nothing. I think it has something to do with the emitter_region section but I cannot figure it out.

Can you show us the code you used for the emitter region?

 

[KevDoesArt]

I changed the x value to room width to see if that would help but did not...

 

[fxokz]

part_emitter_region(global.p1, am, (obj_tree01.x)-20, (obj_tree01.x)+20, (obj_tree01.y)-20, (obj_tree01.y)+20, ps_shape_rectangle, ps_distr_linear);

The region is where you set the x and y coordinates. Give my code a try and tell me what happens.

(Took me 10 years to write that down on my phone xd)

Gave this error. Your code looked solid though. The code itself had no typo errors (the line number didn't turn red)

Im not exactly sure what the reason for the error is but the way you set up the particles seems weird. If i were you i would have just created the particle system in the tree object instead of making it a seperate object.

You should remove the first 2 lines of code if you have multiple trees in the room.

Edit: remove it regardless its useless.

 

[KevDoesArt]

Yeah setting it up in the tree object might be better. It was kind of an after thought while making another system.

 

[KevDoesArt]

I see what the error was - you put global.p1 instead of pl

Ughhh i new it was a typo. Like i said im on a mobile device so its sort of annoying.

Is the particle system working now?

 

[KevDoesArt]

Nope...Still nothing.... Here's the entire code -

 

[fxokz]

Is the object in the room?

edit: man i would just copy all of the code from the leaf object and paste it into the tree. The way you are doing it doesnt seem efficient

 

[KevDoesArt]

It's all in the tree and it is in the room. I could take out the step event I guess. I am using sort of a state machine for the code because I have multiple particle systems and it just makes it easier to duplicate them then copy and paste.
