SetObjectSize(objectid, objectsize) - Gives the possibility to resize objects (smaller or larger) than the original. (Would give some more creativity for custom made maps, specially on Roleplay servers)

SetGameSpeed(gamespeed = 1.0 as default) / SetPlayerGameSpeed(playerid, gamespeed) - Game speed changer.
1 = Normal speed
<1 = Slow-Mo
>1 = Fast

SetPlayerWaterImage(ImagePath) / SetWaterImage(ImagePath) / SetSkyImage(ImagePath) / SetPlayerSkyImage(ImagePath) - Ability to change/replace the sky and water's look with an image (METEOR SHOWEEEER, LAVAAAAA)

ToggleObjectCollision(objectid, true/false) - Ability to change either an object's collision is on or not, if false the player can go through the object (Good for Race DM maps)

https://sampwiki.blast.hk/wiki/DisableRe...icleCollisions - Give the ability to disable unoccupied vehicles collisions too. When 2 or more players are on the same spot and vehicle are switched or spawned at the same time, (mostly racing servers) cars will collide.
