Help texture

hello, sorry for my bad english,

in an old PHASER 2 code, I had that;

this.gameScene=this.add.renderTexture(600, 400);

this.gameScene.renderXY(this.wallSprite, isoPt.x+this.borderOffset.x, isoPt.y+this.borderOffset.y-this.wallHeight, false);

but with version 3 I have this error

this.gameScene.renderXY is not a function

since this function is no longer present on version 3 how to do?
