Not sure what to make of it, but doesn’t seem like a GameMaker bug?

Don’t believe me? Add the following to your fnc_eve():

show_debug_message([typeof(self), instanceof(self), self]);

In 2023.8, this shows

[ "struct","instance",{ ... variables from the instance } ]

In 2024.2, this shows

[ "struct","Object",{ vm_group_call_on_call_field : function gml_Script_vm_group_call_on_call_field, vm_group_call_on_construct : function gml_Script_vm_group_call_on_construct, ...

So what’s that? The global struct? I wonder if this only got half-fixed

Not saying I don't believe you, but that's not what I'm seeing (with GMLive disabled).

fnc_eve() has the following:

function fnc_eve()

{

event_inherited();

show_debug_message([typeof(self), instanceof(self), self]);

}

The child object has fnc_eve() running it its step event. The output window shows the following:

[ "struct","instance",{ ammo_rld_manual_rt : 12, pnce_dur_default : 200, pnce_upkeep_default : 100, pnce_img_spd_ini : 0.25, pnce_ini_vsp : 6, pnce_ini_wsp : 8, pnce_end_wsp : 8, pnce_end_vsp : 4, pnce_enemy_rec : 75, proj_max : 0, use_type : "use_en", addon_snd_sys : "alarm", proj_curr : 0, ammo_rld_amt_default : 1, proj_snd_tri_hv : ref sound 358, proj_fired : 0, brth_phase : 0, brth_duration_def_fr_multi : 130, brth_dur_def_lt : 120, brth_type : 0, cancel_force_dur : 150, alarm_snd_max : 0, fire : 0, can_snd : 1, alarm_snd : 0, ammo_fr_rld_very_slow : 420, can_snd_loop : 1, cancel_allow : 0, proj_dir_l_b : 180, proj_dir_r_b : 0, cancel_force : 0, proj_grav_b : 0, proj_speed_b : 0, proj_dmg_b : 0, proj_img_speed_b : 0, proj_img_index_b : 0, proj_y_offset_b : 0, proj_x_offset_b : 0, can_shoot : 1, proj_inst_b : ref object 484, overlay_sprite_jump : ref sprite 1329, can_fire_hov_rt_default : 75, overlay_sprite_stand : ref sprite 1329, alarm_can_shoot_curr_b : 0, cancel_allow_dur_quick : 30, dir_hov_type : "n"

,...., pnce_upkeep_curr : 100 } ]

I'm not seeing the vm_group_call_on ... stuff. Are you using the same GM runtime as I am (2024.2.0.163)?

I cited what happens in a live-reloaded script after it has been modified once (thus is being compiled-executed by GMLive) - something across the built-in functions now works differently from the last update, and there are no warnings about this in the release notes.

If the same code has different outputs depending on GameMaker runtime version used, that is not intended behaviour.

Thanks for the reply, but I don't know what to do with this response. GMLive is clearly not working correctly with event inheritance. If I report a bug to YYG and tell them this is an issue with this extension, you know they'll just tell me they won't look into how GM works with non YYG extensions.

So is event_inherited just not going to work with GMLive moving forward or what? I'd be happy to file a bug report, but whatever it is that is causing event_inherited to no longer work with GMLive has to be replicated without any interaction with GMLive. If you know how to replicate it and tell me, I can file the bug report.

It’s not just event_inherited - all functions/scripts are now being called with an incorrect self value.

In time, I will figure out what is it that’s broken this time around (GMLive’s a big extension, that’s not fast) and file a bug report, or someone else might.

Either way, I recommend sticking to 2023.8 or 2023.11 runtimes until 2024.2 gets fixed up a bit.
